The driver works now quite well with my hw.

Check the ctfb_README for limits and features.

What about a merge with the old chipsfb.o?
I'm working on my 69030 driver as a separate driver currently, because
of the requirement to use memory mapped IO and avoid all fixed IO
addresses, which makes it incompatible with the 65550. I did look at
your driver, but I decided to base mine on the existing chipsfb.c
because I needed PowerPC support, and because the coding style of your
driver was quite different to existing frame buffer drivers.

My priorities are:
1) Not assume any BIOS setup, as BIOS setup only occurs on x86 hosts,
and only on the primary display.
2) Avoid use of the big-endian region in the chip, while still
supporting big-endian hosts. This is necessary to support the
twin-pipeline mode of the 69030 in future.
3) Support multiple displays. This requires use of memory mapping.
