Great information!

Thanks for the links (digesting the info now).  I'm pretty sure I'm 
seeing the 2D slowdown, as I'll swear the system was drastically slower 
in previous tests (before I ran glxgears), but I figured with all the 
problems and bleary-eyed kernel-compiling I've been doing I had just 
halucinated the slowness or something.  I'll try the various tweaks 
mentoned in the forums, as well as the earlier drivers (for comparison) 
if I can get them to work (I'm not sure if they support the latest 8X 
AGP version of the Ti4200 on my board).
