presumably it is the same driver that works perfectly on linux.

here we have a curious problem.
/dev/ttyd0 is there in the /dev directory.
dmesq puts out the following for sio:
sio0: configured irq 4 not in bitmap of probed irqs 0
sio0: port may not be enabled
sio0: configured irq 4 not in bitmap of probed irqs 0
sio0: port may not be enabled
sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0
sio0: type 8250 or not responding
sio0: [FILTER]
sio1: configured irq 3 not in bitmap of probed irqs 0
sio1: port may not be enabled

now we don't understand how the sio stuff relates to the /dev/ttyd0
and /dev/cuad0

thank you.  we just tried a wacdump on /dev/ttyd0 from x and console -
both times the entire system froze.  what this suggests, i think, is
that the kernel thinks there is nothing there at ttyd0 - in other
words, the tablet's existence has not been picked up by the kernel.

we are presently looking at netbsd where the tablet is supposed to
work. may be we can find out something about how the kernel is done
differently there.
