I found that an upgrade to 2.6.32.6 (with no other distribution or configuration changes) helps enormously. I suppose that this implicates the intel drm kernel code . . .
The only remaining issues are now occasional episodes of blank screen on resume that may be fixed by toggling the video mode. I also notice that there are some tearing artifacts with the new kernel, of course this is unlikely to have anything to do with the original bug. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
