I had tried that first, since it is the default. Googling and the framebuffer 
howto suggested the other formats

When I try video=atyfb:1024x768-8@60, I get even less output:

 atyfb: using auxiliary register aperture
 atyfb: 3D RAGE XL (Mach64 GR, PCI-33MHz) [0x4752 rev 0x27]
 atyfb: 8M SDRAM (2:1) (32-bit) 29.498928 MHz XTAL, 230MHz PLL, 83 MHz MCLK  
63MHz XCLK
 atyfb: fb0: ATY Mach64 frame buffer device on PCI

In all cases, the screen blanks for a moment during boot, then reppears in 
original 80x25 format.


These messages:

 atyfb: MACH64 chips are designed for max 1600x1200
 select anoter resolution
 atyfb: MACH64 chips are designed for max 1600x1200
 select anoter resolution
 atyfb: vclk out of range
 atyfb: vclk out of range

suggest to me that something is going quite wrong, probably 64bit related, 
although that suprises me because I think the ppc folks use this driver quite 
a bit. But perhaps only ppc32.

I'll have a dig in the code and see whats going on.

Analog, so this shouldn't be an issue. I am running linux-2.6.10.
