Xclaim VR pro not supported?

[Andy Wettstein <awettste@cait.org>]

Hi,

I'm trying to set up a blue g3 that has an xclaimvrpro reported like
this from the kernel:
Using unsupported 1024x768 ATY,XCLAIMVRPro at 81000000, depth=8,pitch=1024
Console: switching to colour frame buffer device 128x48
fb0: Open Firmware frame buffer device on /pci@80000000/pci-bridge@d/ATY,XCLAIMVRPro@2

I had to specify video=ofonly to get the thing to even boot.  Now when
I'm trying to set up X windows the best I can do is 8 bit color using
the framebuffer.  I tried to use the ati driver, and it looks like it
works, my windowmanager starts and all (i can tell by using ssh), 
but all I get is a black screen.  

So I was wondering if anyone has one of these cards and has any
information about setting them up for X. 

thanks for your time

Andy
