x86emu is a library and fb-drv is a program, basically just the wrapper
around x86emu with some interface. I think integrating x86emu into
L4Linux or the Xserver is considerable more effort than just let fb-drv
do the switch to VESA then pass-through the graphics memory. Also if
that means tweaking some X driver. Which direct device access (graphics
card) do you actually need?
