I have used kernels 2.6.27, .28, and .29. I've been able to get glxinfo to
show the DRI is in use since
2.6.27, but performance has always been very poor with every kernel. I've also
tried compiling the intel
driver and drm from git since late last summer to try and solve this problem.
Though the debian driver has
worked well for 2D for awhile now and been very stable (though I have been
using experimental packages). I've
had no issues with 2D and thank goodness it works great.
Before I submitted the bug, I compiled libdrm-2.4.7 and git of
xf86-video-intel. This caused a black screen
and nothing being displayed. System was still as able to respond to sysrq keys.
The current debian driver does work with Kernel Mode Setting and I was very
happy to see it work with 2.6.29
and it was great getting a frame buffer running at 1920x1200. However, x.org
pegged one of the cores at 100%
and I had to go back to not use KMS.
I was going to try the new experimental package
xserver-xorg-video-intel_2.6.99.903-1_i386.deb but it requires
libdrm >= 2.4.9.
