That could be interesting. (There are several xc3028 drivers, and
unfortunately the one in trunk is analog-only and incomplete. There's
mrec's drivers, which support analog and digital but either require
changes to core code that'll never be merged or involve a weird
userspace tuner interface that's currently unmerged - I'm not sure how
compatible the latter is with trunk now. There's also digital-only
code lying around somewhere. Finally, I have a port of mrec's
kernel-space driver to the hybrid tuner framework in trunk, but it's
untested with digital and with anything other than the original
HVR-900. The last one is also not currently publicly available.)

The xc3028 has some odd requirements in itself - it seems to need GPIO
twiddling to tune, amongst other things.

(Sorry about the duplicate e-mail - I accidentally replied to sender
