I don't have the hardware directly, and i was reluctant to upgrade the
pegasos patches to 2.6.x, since i heard that radeonfb was causing some
trouble. And i only have a radeon 9000, a matrox millenium II that i can
work on this box.

BTW, i had had reports from Chris Tillman about what seems an fbdev
failure on his 9500 powermac with 2.4.22 kernels. The pci greaphic cards
declares to be a Mach64GX, and lspci gives :

00:0b.0 Host bridge: Apple Computer Inc. Bandit PowerPC host bridge (rev 02)
00:0f.0 VGA comppatible controller: ATI Technolgies Inc 210888GX [Mach64 GX] (rev 02)
00:10.0 Class ff00: Apple Computer Inc. Grand Central I/O (rev 02)

00:0f.0 Class 0300: 1002:4758 (rev 02)
	Flags: stepping, medium devsel, IRQ 25
	Memory at 81000000 (32-bit, non-prefetchable)

Any idea on what is going on here (the kernel works, but there is no
video output).

Friendly,

Sven Luther
