I'm not sure, but I think we're stuck with unaccelerated video until 
the 2.4 Mach64 kernel drivers get fixed (if ever).  I have almost the 
same configuration as you: G3-accelerated PowerCenter with an ATI 
XClaim VR Pro graphics card and I, too, have to set "No Video 
Driver", as well as "Use MacOS video settings" (don't think that's 
the exact text of the option, but I think you know what I'm talking 
about), to get any video in YDL 2.2.  Even using the 2.2 kernel, I am 
unable to get any acceleration.  I'm just glad this machine is used 
primarily as a server so it doesn't impact my usage very much (I do 
run MOL, which is *really* slow graphically, to serve up my HFS and 
HFS+ volumes).
