P35 Neo2 not booting with Crucial Ballistix PC8500 (2.2volts)

Question

This is a psuedo overclocking issue, a mod can move it if need be.
So I got MSI's P35 Neo2 board and I'm frustrated with their whole package.  I install everything and get into Windows and was naive enough to consider running MSI's Live Update, which nuked all possibilities of me getting this to the person I was building it for before Christmas.  If this post seems too wishy-washy, that's why.
The problem is in the RAM I'm attempting to use.  Crucial's Ballistix DDR2 1066 http://www.crucial.com/store/partspecs.aspx?IMODULE=BL2KIT12864AA1065 wants to be run at 2.2 volts, and before updating the BIOS through live update it worked without a hitch.  Now after I ran the update, it gives me errors.
By the way, how in high hell can MSI put out motherboards without documenting them properly?  I spent hours trying to find out how to either change the voltage in the BIOS or do the same in Windows through the Dual Core utility.  The latter ran, but never actually changed the voltage.  And the BIOS - there's nothing in the manual or official online pages that tell you how to change the damn voltage!  It was only after I searched through enough forums that a user suggested using Page Up-Page Down.  Worked like a charm, but wow, if the manual or BIOS had said as much it would have saved me so much time. 
So I do have the BIOS selected at 2.2 volts now, everything else set to auto.  I save and reboot, but no luck.  After three restarts the board tells me in very broken english that my attempted "overclock" has failed with settings reset to default.  I get into the BIOS to find that the voltage is still at 2.2 (which makes sense, otherwise the system wouldn't boot at all, correct?) with all the other settings as they were before.
Question time:
1) The first BIOS revision worked with my RAM perfectly it seemed.  Is there a way to "roll back" without busting out a floppy?
2) Why isn't the system booting?  I know this is a RAM issue because if I break out a slower stick of DDR2 4200 that runs at the more "normal" 1.8 volts, it can get into Windows just fine.  This is how I attempted to set the voltage using MSI's Dual Core utility to no avail.
I've heard good things about MSI motherboards, but these snags I've run into discourage me from using MSI in the future.  Running a board's memory or CPU at higher voltages isn't rocket science, in fact so many memory vendors do it right out of the gate it's incredible you have to do the memory hot swap at all.
Any help would be appreciated.

Answer 1

OK, I've reflashed the BIOS back to v1.0 and now I'm able to boot once again with my Ballistix memory.  Thank God for forum moderators and USB flash tools. 
I might play with the BIOS further - I took a quick look at the revision changes and none really referenced changes in overclocking or RAM compatibility.  As I already explained, I won't be able to get this machine to whom it's intended for until after Christmas so at this point I'm in no hurry as the problem is most definitely a BIOS issue.
Also, after examining my voltages confirmed by CPUz after reloading the v1.0 BIOS, the board correctly detected my memory's stock voltage at 2.2v, which is good to know and lines up with what I've experienced beforehand.
Hopefully they can fix this in a future BIOS revision, but since my Q6600 and RAM appears to be detected correctly at the moment I may never bother.
If anyone needs or wants me to look into this further or to reupdate the BIOS one at a time for documentation/research, let me know, otherwise consider this case closed.
