I tried using 2.6.33-rc7 from the Ubuntu kernel dailies. This kernel was very
slow (unrelated to this bug-- it seemed to be IO or possibly filesystem
related).

I then tried the backported radeon fixes for the Ubuntu Lucid kernel as
mentioned in the Launchpad bug:
"can someone one please test the kernel in the link below and report results
back here ? http://people.ubuntu.com/~manjo/lp507148-lucid/
This kernel has the radeon fixes that might fix this issue."

Using KMS/EXA/compiz, this kernel did not crash compiz nearly as quickly on my
T42, but after prolonged usage compiz crashed with this in dmesg:

[15040.618564] [drm:radeon_object_busy_domain] *ERROR* radeon: failed to
reserve object for waiting.
[16936.764884] [TTM] Failed moving buffer. Proposed placement 0x00060004
[16936.764891] [TTM] Out of aperture space or DRM memory quota.
[16936.764895] [drm:radeon_object_list_validate] *ERROR* radeon: failed to
validate.
[16936.764898] [drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation !
[17015.483860] Unpin not necessary for d095f600 !

Using plymouth with KMS results in a system lockup very early during boot (with
no output that I could see).

Marc Deslauriers mentioned in the Launchpad bug that his T30 (16MB of video ram
as opposed to my 32MB) did not show any significant improvement with the
xorg-edgers packages and backported radeon fixes.

I might also mention that connecting my T42 to an external 1680x1050 monitor
(my LCD is 1400x1050) would make compiz crash readily when using xrandr.
