The xf86-video-cirrus driver already supports the 5434, it shouldn't be hard to 
get it going on x68k. I guess this is the VL variant with some goo added to 
make it talk to whatever bus the x68k uses.
Either way, all you need to do is to make Xorg build on x68k ( not difficult ), 
add a way for the Xserver to map the relevant IO space so it can access the VGA 
registers. Check out what shark is doing, it's pretty much the same problem ( 
VL chip, non-x86 CPU etc. ).

have fun
