           Summary: Kernel Mode Setting Fails on Radeon X700
           Product: Drivers
           Version: 2.5
    Kernel Version: 2.6.35.5 x86_64

          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
        AssignedTo: drivers_video-dri@kernel-bugs.osdl.org

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.

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.

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.

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.

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!

FWIW, the ddx has the pci id correctly associated with rv410, so it
looks like it was just improperly ported to the drm.

The lockups can be the polling bug in
