Description of problem:
I'm having some problems with getting X to start on a PowerMac G4 with an ATI Rage 128 video card with 16MB Video RAM... sometimes on boot, I get "aty128fb: Invalid ROM signature 1111 should be 0xaa55" and it hangs, and sometimes it gets the error, but is able to get past it, but then X can't start, with an error of (EE) R128(0): Cannot read V_BIOS (5) and then (EE) R128(0): No DFP detected.
/etc/xorg.conf has the video card configured thusly:
VendorName "Videocard vendor"
BoardName "ATI Rage 128"
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Start FC4 in runlevel 5 or issue init 5 command
Actual Results: Either the system hangs with the Invalid ROM signature error or it boots but X fails to start.
Expected Results: The system should boot cleanly and X should start properly.
Here is the output from lspci:

I have posted this to X.Org as bug 3601 as you suggested:
However, there still is the problem with the fact that I always get "aty128fb:
Invalid ROM signature 1111 should be 0xaa55" on boot, and sometimes it can't get
past this point at all, to say nothing about booting the kernel and getting to X...

This could be a bad BIOS on the card, which is what the message is implying.
If you're having kernel problems, you should also report a bug against the
Hope this helps.
