Xorg.log of a crashing session

Hi All,

my currently built kernel doesn't like to bring up KMS (and hangs somewhere; to
be investigated), so i booted up an older distribution-kernel and X gives me
trouble. :-)
Basically X sets the mode, draws a cursor, sometimes even gets as far as
setting the background picture (so client gnome-settings-manager i think), and
then crashes, so that i have to Alt-Sysrq-R to even switch back to my orginal
text console (on which I cannot see anything of course, as the mode doesn't get
set back).

I'm using
  libdrm        master          790097c51330090b2b7b90429b9ab8ddf259fd8e
  mesa          master          43b3b745e4d893b64d6331cb6183f8615e613f66
  X-Server      1.6.1-1 (debian package)
  xf86-video-ati kms-support    2174d880152ad5c47e2a28b3e9ab65a8d319a9af and
later
This mesa is also broken for me (glxinfo even segfaults) but that should not
matter here as nothing this early in the session does GL (no compiz here).

git bisect identifies the culprit as:
  [2174d880152ad5c47e2a28b3e9ab65a8d319a9af] radeon: consolidate more code in
macros/inline.

waiting for X server to shut down

Xorg.log is also attached.

I'm not sure what should define the radeonGetPixmapOffset symbol, maybe I'm
compiling something wrongly ?

Thank you for your consideration, keep up the awesome work !
Ciao,
