Sorry... I've been tied up with work a lot lately and haven't had a lot
of time to spend on it.
I still haven't been able to overcome the problem with the resolutions
at 108Mhz, otherwise it seems to work pretty well. I expect it will be a
while yet before I can spend any serious time on it, so if someone else
wants to work through the problem and submit a patch, feel free.
