Problems with new nVidia drivers 91.33 and 91.31

I have run into a problem with the 9x.xx nVidia drivers using a
GeForce7300GS PCI-x card - my DirectX application fails when it calls
GetDeviceCaps() with D3DERR_NOTAVAILABLE. This is the same error which
is returned if no driver is installed at all. If I simply replace the
nv4_disp.dll and nv4_mini.sys files with ones from an 8x.xx series
driver, the call succeeds. Has anyone else seen this problem?

I also had some weirdness starting with the 8x.xx series nVidia drivers
where it would BSOD immediately before starting FBA, but that was
remedied by importing gobs of registry keys from an XPPro install. See
this thread:

I can recreate the problem with the 9x.xx drivers under XP Pro if I
install the driver, but attempt to run my application _without_
rebooting. After rebooting, the call succeeds. Any ideas? This
particular problem never occurred before the 9x.xx series. I am
looking into post-reboot registry changes now, but so far, no luck. As
always, any help would be much appreciated!

Thanks,

Jason
 
Update - I had DirectX 8.1 binaries on my XPe system, and it appears
that the 9x.xx nVid drivers need Directx 9.0 or higher, at least on
Windows XP Embedded - can anyone else confirm this?
