Running a Lenovo Thinkpad L520 here, too.

Noticed this bug on Ubuntu 12.04 amd64 alpha 1 LiveCD. Also, on Ubuntu 11.10 (amd64) a vanilla 3.2.0 kernel compiled from kernel.org sources has the exact same symptoms. No amount of twiddling with framebuffer modules, initrds and such seemed to help. Adding kernel boot option modeset=0 helped, but only allowed 1024x768 resolution.
