Great. I'll test it later today.

I've never tried 24bpp because of limited acceleration support. I haven't 
even bothered implenenting 24bpp acceleration in the DirectFB driver.

My only todo item is mtrr support. I have a patch which simply tries to 
add fix.smem_len sized wrcomb mtrr. But that will only work with 
power-of-two memory size. Also it won't work with a 8MB card when the 
auxiliary aperture isn't used. Maybe an 8MB wrcomb mtrr + an overlapping 
uncachable mtrr covering the register page might be better. Will that sort 
of thing work on all systems?
