I discovered one app that wasn't drawing at all well (java based) and when
trying to debug I discovered that I hadn't turned UXA on in xorg.conf.
Turning it on fixed that problem, so all-in-all I'm pretty happy with using
the 2.6.30 kernel and the 2.7.1 xserver-xorg-video-intel driver. I'm
working on the suspend issues. I've added "xrandr --output VGA1 --off" in
my /etc/pm/sleep.d/30xrandr file (this basically turns off the external
monitor - yours could be named something other than VGA1), and it seems to
make it possible to suspend & resume.
$ cat /etc/pm/sleep.d/30xrandr
# reset xrandr settings on resume
# we should be able to remove this when KDE properly supports dual monitors
case "$1" in
# turn off external monitor, as we can't resume at all with
# it active
xrandr --output VGA1 --off
# External monitor settings are handled by krandr, except
# actually making it an extension
# of the internal, rather than a mirror
xrandr --output VGA1 --auto --right-of LVDS1
*) exit $NA
