Photoshop CS5 - Current Users of 10 bits per pixel color

Question

Hello,
I'm looking for feedabck from anyone who currently has a full 10 bit display pipeline using Photoshop CS5.  I've got a question in on another thread about info on 10 bpp hardware support but I wanted to also start a new thread to get comments from users who are already there.
First and foremost I would like to know what graphics card you are using, and second your monitor and the color space you're using.  Info on drivers, calibrations tools you may have used on the monitor, performance differences you may have found going from 8 bit to 10 bit, your OS, etc. would also be appreciated.  Of particular interest would be anyone who has been able to get a non-workstation graphics card working with 10 bits all the way through.  I believe this is only possible with DisplayPort, although I have seen information that workstation level cards can do it over DVI.
Please!! no Luddite style comments/questions about "why anyone would want to do this", or "what a pain it will be", or how "8 bits sRGB color is perfectly adequate and wonderful" for everyone.  I've essentially been there and done that in terms of reading these comments and I have less than zero interest in hearing any of them, no matter what your level of experience.  If I stated this as strongly as I would like I'm sure I would violate forum rules on language, so please respect my wishes here and start another thread to bash 10 bpp or wide gamut color in general.
I'm only interested in getting tips on what is needed to make it happen.  Others who are not there yet but with legitimate interests in 10 bpp color feel free to expand on my questions.
Thanks.

I don't have a 10 bit pipeline myself, BUT...
I did run across one interesting tidbit with regard to using OpenGL with Photoshop through ATI video drivers...
A while back, as I was developing a plug-in that uses OpenGL, I observed that the ATI Catalyst driver (for my Radeon HD 4670 card) was choosing a deeper format for textures than what was requested (16 bit half-float instead of 8 bit integer) but only when my plug-in was running as part of Photoshop.  When I ran the plug-in in another app it did not do this - it stayed with an 8 bit texture depth instead.
It turns out (confirmed by an ATI engineer) that the video drivers were actually detecting the application being Photoshop and making different decisions - presumably to increase the quality of the display specifically for Photoshop to support the high quality 10 bit color pipeline you seek.
More info here:  http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=281068
The key thing here is that prior to this discovery I never suspected that a video driver might do things differently depending on what application is calling it.
Good luck putting together a system that gives you that higher quality display.  I'll be keenly interested in reading about your discoveries here.
