sure. i attached three files:
isight-good.txt, isight-bad.txt, isight-good2.txt
this is three reboots in a row from like 10 minutes ago. the first
boot into linux was actually rebooting from OSX...first cold boot
today directly into linux had the right GUID.

yes, sometimes only. it seems to be related to reboots, but i don't
know what exactly triggers it. rmmod/modprobe doesn't trigger it.
also, when the wrong GUID is reported, the only way of fixing it is
to reboot. it really is just the GUID. even when the wrong one is
reported, the device works just fine.
i started with a plain ubuntu 9.10, kernel 2.6.31 which was supposed
to fail, so i upgraded to a 2.6.32-rc8 to fix the iSight and some other
things, just to see it fail again. a reboot later and it worked, some
time and reboot later it failed again...
