Dear Maintainer,
Copy-pasted:
me@mybox:~/fw-radeon$ romheaders R420_cp.bin
Image 1:
PCI Expansion ROM Header:
Signature: 0x0000 (Not Ok)
CPU unique data: 0x00 0x00 0x42 0x00 0xe0 0x00 0x00 0x00
0x00 0x00 0x40 0x00 0xe0 0x00 0x00 0x00
Pointer to PCI Data Structure: 0x0000
Rom Header error occured. Bailing out.
This is for the R420_cp.bin in firmware-linux-nonfree. I used another rom from
'net and though no GPU acceleration (noted disabled in dmesg), at least that
one doesn't lock up my system at boot. At boot with this R420_cp.bin from
firmware-linux-nonfree I get a black screen and system lockup, though X was
previously working fine (no other changes) before the package's installation.
Here's copy-paste for my rom from 'net for comparison:
me@mybox:~/ati_ret_x800xt$ romheaders R420_cp.bin

Revision Level of Code/Data: 0x0000

Platform specific data for Open Firmware compliant rom:

Note: I still do NOT get GPU acceleration by any means, though using a rom that
is not apparently volatile.
Thank you.

You are confusing two entirely different types of firmware - GPU
microcode and PCI expansion ROMs. The microcode is 'correct', or at
least it is the same microcode that Linux has used since 2008.
The problem you're seeing is in the radeon kernel or X driver. It is
triggered by installation of this package because they won't use GPU
acceleration if there is no microcode available for it. You can open a
bug against the kernel, but I'm afraid it is very unlikely that
radeon's issues with old PowerPC machines will ever be fixed.
Ben.
