Ok, which ones specifically? :)
Without some of those, battery use from the driver has been bad in the past,
but I don't know which one does what exactly :)
- pcie_aspm=force
- i915.i915_enable_rc6=7
- i915.i915_enable_fbc=1
- i915.semaphores=1
- i915.lvds_downclock=1

On debian testing and unstable, it's the latest:
legolas:~# apt-get install xserver-xorg-video-intel/unstable
Reading package lists... Done
Building dependency tree
Reading state information... Done
xserver-xorg-video-intel is already the newest version.
Selected version '2:2.21.15-2+b2' (Debian:testing [amd64]) for 'xserver-xorg-video-intel'
But now that you mention it, I just found this, so I'll try this out:
legolas:~# apt-get install xserver-xorg-video-intel/experimental
Reading package lists... Done
Building dependency tree
Reading state information... Done
Selected version '2:2.99.917-1~exp1' (Debian:experimental [amd64]) for 'xserver-xorg-video-intel'
On top of being bleeding edge enoug not to be in debian unstable, does it have
performance enhancements that you are hopeful will help my situation?
Thanks,
Marc
