Hi all,
 
Well, I bought an "ATI Xpert 98 AGP X2" video card and have managed to install Plan9.  FWIW, the chip itself says "RAGE Mobility-L" although I'm using it in a Dell deskstop.
 
(As an aside, the install procedure was very pleasant.  Certainly more humane than FreeBSD.  Reminded me a lot of the BeOS [RIP] installer.)
 
However, the display is messed up w/ left-hand side of the screen repeated and the right side consequently falling off the right-hand side of the screen.  Can I fiddle w/ VGADB to fix this?  Or do I have to "upgrade" my video card yet again?
 
Thanks in advance.
