aty128fb weirdness

[Chris Boot <bootc@worldnet.fr>]

Hi all,

I only just decided to reinstall Linux on my Apple iMac DV SE/500 with an
ATI Rage Pro 128.  Last time I used Linux on this machine was when kernel
2.4.2 was the latest.  Now, when I try to use the native kernel driver for
my graphics card, all I get is a black screen.  I can type blindly into the
console or login through the network.  I double-checked all my kernel
arguments and didn't find any mistake whatsoever, and enabled the debug code
in the aty128fb driver, all to no avail.  I also tried several kernels,
ranging from the one included with my distro (a patched 2.4.10), 2.4.16,
2.4.17, and 2.4.18-pre3.

Quoted below is a dmesg of a boot using the driver with debug code compiled
in.  This is an iMac whose video modes are 640x480@116, 800x600@95, and
1024x768@75.  Currently, the only way I can get console video is if I force
the kernel to use the OpenFirmware frame buffer, which is locked to
1024x768@75 in 8-bit color mode, and is way slower than what the native
driver could do.

If anyone can figure out what's wrong, I would be forever grateful.

Thanks in advance,
Chris Boot
