Some of these fixes were to
extremely important areas (get_user_pages, a fix for
framebuffer-scrolling issue, and more).
It goes against common sense (to anyone with kernel knowledge) to use the
console framebuffer anyway.
The duration of kernel locks and the CPU expense of blowing bitmaps around
like that are shocking.
Seriously. Use text-mode consoles, or a native AGP-driver a la nvidia, ati,
or whatever. But using a "stupid" framebuffer driver is asking for hardcore
latency blow-outs.
