I've tryed to rmmod uvcvideo, videodev and v4l1_compat but on current git suspend still hangs in the same way (screen black, backlight on, fans at full speed, no response to ping and... nothing in the logs).

Please try the current mainline with acpi_sleep=nonvs in the command line.

With: acpi_sleep=nonvs console=tty0 (kubuntu defaults to quiet spash) I was able to complete 3 suspend/resume cycles before hitting an hang. After a power cycle I was able to suspend again, so it seems that, albeit racy, this cmdline has a positive effect. With: acpi_sleep=nonvs or console=tty0 alone I've never been able to suspend (only the combination of the two makes a difference).

Have you checked the thread started by Thomas Meyer : 2.6.35-rc6+: i915: Bisected regression He describes something similar to your problem (and I was having the same), and the solution he indicates worked for him, for me, and a third person so far.
