Not to be too dramatic, but getting my video card to
work on my PowerMac 7500 running debian is killing me.
I apologize in advance for the length of
this post.
Here are the os/hardware facts
1) OS - Debian woody
2) kernel = linux-2.4.21-ben2
3) the kernel has the atyfb and the aty128fb modules
compiled into it.
4) the ATI card I believe is a NexusGA, because it
matches specs on the ATI website. But the chip
on it says "ATI Rage 128 3D AGP".
5) the card is installed in the first PCI bus on
the PowerPC 7500
6) the Xserver is 4.0.1, using the "ati" driver for
the card driver
7) one of 2 monitors, either a Dell M990 (17") or a
Apple 15" Multiscan. Although the video card has
2 video parts (one mac and one VGA), I only
attach one of the above monitors to it.
I have no problems getting either of these two working
on the framebuffer using the ATI card at atyfb. dmesg
output shows that the kernel reconizes the ATI
in the following way:
Aug 3 13:27:35 anima kernel: atyfb: using auxiliary
register aperture
Aug 3 13:27:35 anima kernel: atyfb: 3D RAGE PRO (BGA,
PCI) [0x4749 rev 0x7c] 8M WRAM, 14.31818 MHz XTAL, 230
MHz PLL, 100 Mhz MCLK
Aug 3 13:27:35 anima kernel: fb1: ATY Mach64 frame
buffer device on PCI
Of course, I encounter problem with X using this ATI
card. X recognizes
the card as follows:

Note: I have followed the "ati" driver options
instructions to the letter. I cannot add "Clocks"
option for this card because they will not be
recognized. I have not added the "ChipID "mach64""
option because it does not work with this card. I
have also tried using the "r128" driver and it
doesn't work at all with my card.
Finally, these are the modelines I used for this card:

I calculated these modelines -- following kernel
documentation -- from the file /etc/fb.modes found in
Debian, which according to its header says they were
derived from the ATI Mach64 documentation. I have
also calculating modelines by hand using the howto.
Most on the time, the image produced by these
Modelines either
a) exceeds the signal the monitor can receive,
b) produces a cross-hatch artifacted display,
completely unreadable
c) or gives a strange overlapped-duplicated image of
my desktop with no arrow (the most promising).
At this point, I have no idea were to go from here.
If anybody has any idea how I can solve this, I would
greatly appreciate it. I would really like to get 2
monitors going and was looking forward to some speed
improvement with the ATI card on my large monitor.
