    hm, are you using the xf86-video-intel git-branch "2.7"? if i use that,
    i need a kernel fix queued in eanholts for-linus git-tree or else i
    also get unusable X.

    i assumed that this was because of some not-yet-released fixes
    on the 2.7-branch which will get released as soon as erics queue is
    merged? but i didn't double check ... maybe the released version is
    also broken in this regard for me....
