KMS/composite freeze logs from Martin Pitt

It had worked fine for some weeks (KMS+compiz) on my i945, but now it's back. I'm following Ubuntu's "xorg-edgers" archive which has very current snapshots of upstream. Unlike most regressions that I see, this one isn't just a temporary glitch, it's been broken for over a week now. It now freezes about two seconds after resuming, not several minutes, but otherwise the symptoms are very similar. Should I open a new bug about this, or is it the same? Logs attached (dmesg, gpu, registers, Xorg.log). My current versions:

  Linux 2.6.30 final, with git pull from anholt/drm-intel.git (commit 03d606991)
  libdrm from 2009-06-06 (3d4bfe8c)
  mesa from 2009-06-13 (18af7c38)
  intel from 2009-06-11 (6d062e9e)

I tried the following combinations:

 - KMS, X.org session with compiz: usually freezes; seldomly it survives first suspend, freezes on second
 - no KMS, X.org session with compiz: ok
 - KMS, VT only: ok
 - KMS, gdm only (no composite): ok
 - KMS, X.org session with metacity (no composite): ok
 - KMS, X.org with compiz, switch to VT1 before suspend: ok on resume, often freezes as soon as switching back to X.org
