Update: Completely disabling framebuffer on the kernel command line
(nofb nomodeset nosplash) solves this problem for me too.
On a side note, booting with nofb nomodeset also allows me to use the
radeon driver instead of radeonhd.

[RV515] radeonhd is incompatible with KMS.

Hi,
I was using radeon with good success under Ubuntu 9.10, but it didn't
work at all after upgrading to 10.04, so I switched to radeonhd. Thanks
for reminding me - I'll try to reproduce the radeon problems and file a
separate bug report for that (Mobility X1400 seems rather ill-fated in
lucid).
The above attachment is a copy of /var/log/dmesg. I just noticed the
current dmesg output contains a few additional lines:
