Ah, so it's an artifact of the new 9000 series drivers.  Yes, this
has improved things.   Still can't play HDTV mp4 and wmv videos
without some stutter.  They also have problems (but fewer) in
the standalone players, though CPU is not pegged (not nearly on
my core 2 duo) so I expect those problems are deeper, but not
as important.

Curiously, the nvidia program on power fail reboot rewrote my xorg.conf so I
hope it doesn't do that again.

Now I'm off to find out why "mem" doesn't show up in /sys/power/state.
Sigh.   And the cause of the wavering for 20 minutes after boot or
wakeup from dpms.  That sounds like an artifact of the card warming
up or something but it wasn't present under the old drivers so I
am going to pound on it a bit more.
