We had an old project that used an Analogue Devices 0800 chip attached
to GPIO lines of a coldfire processor.
the driver is available for the 2.0.x linux kernel, and could fairly
easily be ported to 2.2.x, 2.4.x or 2.6.x kernels.
Not sure if AD sell the hardware anymore, but the driver is in our
snapgear linux distribution
snapgear-3.1.1/linux-2.0.x/drivers/char/dac0800.c
from
ftp.snapgear.org/pub/snapgear/src/snapgear-3.1.1.tar.gz
