I believe Ben already answered that one, but perhaps it's not that obvious if one does not have experience with nouveau. The PRAMIN region (in this context) is the last 1MiB or VRAM. As the card is POSTed/initialised the VBIOS is copied in that region. As you can see on x86 your card is initialised, unlike on PPC. Regarding your earlier question(s) (despite that I'm not Ben) > 1.

Afaict there as need (close to) 0 work done understanding what needs to be done, let alone writing the patch(es). > 2.

No offence/disrespect, but I think you are underestimating how deep the waters are(could be). Even if on the nouveau side everything is fixed, there has been a few issues in mesa (as pointed by Ilia) wrt big endian machines, which afaict are not resolved. Maybe you can take a look and fix (if needed) the software rendering on BE machines. That should cover some of the mesa bits :) -- You are receiving this mail because: You are the assignee for the bug.
