Let's get the miniport loading first. I've updated VideoPrt.sys to print 
a few more debug messages that could be usefull. If we get the card 
detected, the next thing would be propably implementing the AGP support 
(Note: AFAIK On Windows it depends on external filter driver and that 
would require a bit of work, because our PnP manager doesn't support 
filter drivers yet...).

We must get the miniport loaded first, otherwise Win32k can't work and 
behaves like this with the crash.

The last line should be
HKLM,"SYSTEM\CurrentControlSet\Services\Vga\Device0","InstalledDisplayDrivers",0x00010000,"vtdisp" 

Otherwise, it's O.K.

I've downloaded it, so I have access to these files...

Yes, OpenGL driver.
