Blue screen of death - Windows7 on 24" iMac (white) with 7600GT gfx upgrade

Question

I'm thinking this might be a warning to people in similar situations...haven't got a workaround yet...so I installed Windows7 beta (genuine 7000 public build from Microsoft) through BC. Went fine no probs at all, until it wanted to fire up windows with the proper GUI for the first time...got a bluescreen saying that nvlddmkm.sys (nvidia driver) was the culprit. That is as far as I can go. Tried reinstalling, tried to allow unsigned drivers, tried to force 640x480, safe mode, tried them all, and BSOD every time.
Also tried using "last known good settings" and it just restarts without warning. Nothing I have done can get it past the screen that says "Windows is getting ready to run for the first time".
I've installed without issue via Fusion and that is working so I know it isn't the install disc I made, but I guess this is just a heads up for those with the 7600GT...don't install (unless there is an answer forthcoming of course)
Cheers

Answer 1

OK, I have a workaround, and it seems to be stable enough atm (I'm using it with chrome to submit this so I guess it is ok)
It is messy but as of now I've been able to rate the computer (with the experience thingy) which has always BSOD'd on me before even if I have been able to get to the desktop so here goes:
Method 1
you need MacFuse - http://code.google.com/p/macfuse/
you need 3G-NTFS (Fuse plugin) - http://www.ntfs-3g.org/
ok...so you are bluescreening and can't even fire up for the first time? even when you go to safe mode it says "you need to finish setting up windows first".
go back to MacOS, install Fuse and 3G-NTFS and reboot. Go into the 3G control panel and after authenticating you should be presented with a "mounted volumes" dropped down with your volume selected. If so close the panel and open your drive. Navigate to Windows:system32:drivers: rename nvlddmkm.sys to nvlddmkm.sys.old or just delete it. Close everything down and reboot into windows7. You should now get past "starting windows for the first time" and into some awesome windows7 640x480 action!
Method 2:
Reboot PC and rapid-fire tap F8 key to bring up the safe mode menu. Go to safe mode with command prompt and use your DOS skills to rename or move the offending file. (Writing this I can't remember if I was able to boot into this mode without "running windows for the first time")
Once loading the desktop I tried a few things...this is what ended up working for me:
Grab your MacOS install DVD and insert. When it pops up asking to run setup ignore that and jump into regedit. The solution offered elsewhere in the forum worked well for me which was:
Change
Computer\HKEYLOCALMACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
from 6.1 to 6.0
exit, click on the run setup option and allow BootCamp to install. Reboot and either download the 2.1 update to bootcamp beforehand or allow it to update. Let it do it's thing.
Last thing is to run windows update, under optional install there should be an nVidia update, install it....and voila! more stable than I've seen it yet.
