It's not in my tree (2.2.18), the only documentation I could find was
the source code. Anyway, it seems that atyfb gets a precendence over
vesafb and screws up the LCD. Right now I use the following kernel params:
video=atyfb:off video=vesa:mtrr vga=795

For reference this is Dell Inspiron 5000, lspci -vv says this:
