Mach64CT 2MB PCI VGA for PPC/Linux?

[Henry A. Leinhos]

Hi All,

I pulled an old ATI Mach64CT (2MB)  from an old PC the other day 
thinking I could multihead my DualG4/450.  I've tried to setup my 
XF86Config-4 several ways for Xinerama, but  I just get stripes on the 
second display (a ViewSonic vp140 LCD), and error messages in the 
XFree86 log file reporting problems with the BIOS.   I've tried the 
"ati" driver, as well as the "fbdev" XFree86 driver with no success.

At startup, the system recognizes the card and assigns fb1 to the 
device, and XFree86 sees it as well.  At this point, I'm not sure if the 
PPC can use this card at all.  Here's an example of what "XFree86 
-configure" generated:
