Frame Buffer problems

[Wes Keck]

    Just had a quick question. I'm running YDL 2.3 on an s900 (marginally
supported, I know). The video card I am using is an ATI Xclaim VR TV, and
that is going to an Optiquest V73 through a small adapter. What frame buffer
should I use? Some references point to an 'atyfb' but for some reason when I
tell the Xserv to use that, it tells me no known module exists by that name.
The 'ati' setup produces a skewed image much like the synch rate has been
oversampled. Is this because of the adapter? Is there anything else I could
try? 

Thanks for your time
Wes
