The bridge module would have to somehow interpose on the
real calls with wrappers that copied the structs to the
other format - I'm not sure exactly how to do that though.
One thing that may help is that pretty much only the Xsun
drivers would still be using the cfb libraries, since all
the Xorg ones are ported to fb. (Though I don't know if
that's true for the ones the SPARC group is actually porting.)

Actually, that's pretty much the mode I saw the Xorg on XVR-2500 in the
first time I went to see it running - I think the problem involved the
colormaps, but don't remember the details. Run xdpyinfo and see if the
pixel sizes and RGB masks look correct.
