Beside visual corruptions and hangs I also experience complete system
hang ups (no reaction until hard reboot) and occasional kernel panics. I
therefore wonder why this report does not receive higher prio?

The same here, previous kernel 3.5.0-25-generic works without problems,
3.5.0-26.42 hanged just now:

root=/dev/mapper/System-root ro quiet splash i915.i915_enable_rc6=1 vt.handoff=7

This affects me, but in my case I'm running Ubuntu 12.04, and the
problem seems to be with kernel 3.2.0-39. Booting to kernel 3.2.0-38
seems to have fixed it.

Another note, when these hungs happen, I get graphic corruption (usually
in the fonts/text).
