I can't try them on my PC due to it having a crap graphics card (I'll
probably buy a new one soon because it's bugging me), but the results on
the NetWinder were:

8bpp works fine.
16bpp silently fails (the initialise call fails).
24bpp fails with:
bogl-cfb.c:54: memset_var: Assertion `(((unsigned int)dst * 8) % b) == 0' failed.
32bpp seems not to work at all on the NetWinder.

Another thing I noticed is that the FBIOPAN_DISPLAY ioctl always fails
on the NetWinder (I think the hardware doesn't support it), so you should
probably remove the test for the return value, as it causes bogl to die
when the ioctl call returns -1.
