Using the xorg-edgers drivers and Manoj's kernel seemed to help
somewhat. It took longer to crash compiz but ultimately it did crash
with the same error. :( This is with no xorg.conf file, with KMS, with
EXA and with compiz. Attaching an external monitor with a higher
resolution than the laptop (eg 1680x1050 vs 1400x1050) will crash compiz
readily when using xrandr (same out of memory errors).

Installing plymouth makes the laptop completely unusable-- with a hard
system lock very early in the boot process and no text displayed on the
screen. Only the backlight is on.

As mentioned, a usable, but a regressed configuration (over Jaunty,
where compiz is usable) is to disable KMS, use XAA with RenderAccel off,
disable desktop effects (compiz) and remove plymouth.

For more details, see my extensive comments in the upstream bug.
