Full 'lspci' Output

The kernel fails to set any video mode when booting, reverting automatically to a standard VGA console.  X.org does not succeed at initializing video with the radeon driver either, so this issue is not limited to the kernel DRI.

Comment 7 Dave Airlie 2010-09-24 03:21:22 UTC 
can you verify you haven't flashed the BIOS yourself thinking it would provide amazing speedups?

because the bios and gpu seriously don't seem to match.
Comment 8 squeept 2010-09-24 19:02:31 UTC 
Still using the stock video BIOS.  It's ironic, because I originally selected this particular card for price and compatibility rather than performance.

As far as I'm aware, this was one of the last cards to be issued in this X550/X700 series.  I thought it was marketed as an X800, though my memory may fail me.

It does work correctly in Windows 7 out of the box, so presumably there's nothing actually wrong with the video BIOS.

The file you posted appears to be a patch against 'include/drm/drm_pciids.h'.  I shall try applying it later, rebuilding the kernel, and return to report the results.
Comment 9 Alex Deucher 2010-09-24 19:25:55 UTC 
According to the internal pci id database, 0x5657 is indeed an rv410.  I suspect it must have been added wrong initially and no one ever ran into it or reported problems with it until now.
Comment 10 squeept 2010-09-24 22:40:18 UTC 
Huzzah!  Patched kernel works great.  Switching between VT and X is now extremely fast :)

Even better, X now loads and runs with the 'ati' driver.  3D also seems to be working, although it's a bit unstable (some games lockup the system after a few minutes).

Thanks for the fast and effective response!
Comment 11 Tormod Volden 2010-09-25 13:22:16 UTC 
The lockups can be the polling bug in https://bugs.freedesktop.org/show_bug.cgi?id=29389 which I see on my 0x5653 (both r300 and r300g).
Comment 12 Alex Deucher 2010-09-25 18:14:10 UTC 
FWIW, the ddx has the pci id correctly associated with rv410, so it
looks like it was just improperly ported to the drm.
