I got XDirectFB working with xorg-server-1.0.2 quite nicely.

I replaced the fbcmap #ifndef test with #if 0. It would be nice to fix 
this without having to patch fbcmap.c but I have to figure out if 
defining XFree86Server in xdirectfb-config.h would have unwanted side 
effects...

I also disabled most extension via xdirectfb-config.h. This fixed the 
apps geting a BadRequest errors. I don't know exactly which extension is 
the culprit. I had to re-enable LBX because some generic code would 
segfault with it disabled (that might be a bug in the generic code). 
I've attached the xdirectfb-config.h I used.
