Same problem here with the console. Apparently using framebuffer
drivers may cause this, see [1], but I'm having the problem also with
boot parameter nofb.

Yep.

Ah yes, this has been familiar to me during the few days I've tried
the latest stuff. Could you file a bug report about this one? I wasn't
sure if it was only my problem or not.

I can only speak about testing - you should get the latest drm/libdrm:
git://anongit.freedesktop.org/git/mesa/drm
plus latest Mesa & DRI:
http://gitweb.freedesktop.org/?p=mesa/mesa.git;a=summary
You also need the to-be-1.5 of Xserver:
git://anongit.freedesktop.org/git/xorg/xserver
and latest Intel 2D DDX driver:
git://anongit.freedesktop.org/git/xorg/driver/xf86-video-intel

When configuring the last one, make sure you see "DRI_MM" "yes".

As you go, you may try to think of enchancements to
http://wiki.x.org/wiki/ModularDevelopersGuide and
http://dri.freedesktop.org/wiki/Building. At least the former should
IMO have mentions about libpciaccess and maybe some newbie's summary
for people wanting to test the newest stuff. I may be adding some of
this also but feel free to add any notes you think may help others.
