Comment 15 for bug 1434581

In an attempt to narrow it down, I downloaded some more kernels from mainline to test. I reloaded the machine with 12.04 and tried 3.11.0-26 (via linux-generic-lts-saucy meta) and 3.12.0 from the mainline repository. 3.12.0 is slow like 3.13 and 3.11.0-26 performs fine as noted in the original report.

The only commit I could find involving vesafb between those was in 3.12-rc1, but I could be missing something.
