You may be right.  Found some traces indicating that:

	http://bbs.archlinux.org/viewtopic.php?pid=678831#p678831

Looks like a kernel regression then.

On the other hand, it might just be me.  I may have missed something.
Come to think of it.  Do I need to tell the kernel on the cmdline to not
use all RAM (reserve some RAM for video)?

On the same thread (see above), I found some info about another (Intel
closed source, of course, what else could one expect?) driver, IEGD, for
which Intel doesn't advertize gma500 compatibility, but others do:
