I'm using the gx1fb framebuffer for the geode. However, since this problem
occurs even when the VT outputting the text is not active, I don't think
it's fb related.

The latency output is just a bunch of numbers. :P

Here is some output with the latency -p 500 command, and halfway through it
I put a 100% load on the cpu.

== Test mode: periodic user-mode task
