OK, I did this (2 places) and now the new imsttfb.c compiles fine
into the kernel. However, using the video=imsttfb BootX argument
appears to do nothing. IOW, when starting X, the FBDev messages
indicate that there is no IMS acceleration available, and it runs
unaccelerated, as if I had checked "no video driver". A quick test of
the kernel with the old imsttfb compiled in and the identical BootX
args shows FBDev recognizing and starting acceleration, but with the
old results (unuseably fractured graphics).

I'm sorta in over my head here, but can still take directions well
:-) Any additional comments?
