I have an HD3000 working under 2.6.10. Minor changes to calls to
pci_save_state and pci_restore_state and it's working fine.

With lots of help from Taylor via IRC, I got the Skystar card working
under Myth. I'm putting my notes here for the benefit of others who
may be trying it. Of particular note (to only a few, perhaps),
pcHDTV doesn't yet have drivers for the HD-3000 that compile against
the new kernel 2.6.10.

In the process of compilation, don't forget to copy the card's firmware:
e.g., cp path-to-dvb-kernel/firmware/dvb-fe-nxt2002.fw
/usr/lib/hotplug/firmware
Taylor's azap utility is helpful in determining whether the card is
fully loaded and getting signal.
(download his make_atsc_chanconf.pl and azap package; perl
make_atsc_chanconf.pl [zipcode] > ~/.azap/channels.conf ; azap
[station callsign] )
Recompile myth, being certain to include the DVB options and the
correct path to dvb files in settings.pro.
Then follow the illustrated guide to setting up a dvb card
<http://www.digitalregime.com/mythdvb/setup/>. Broadcasters'
careless attitudes toward whether they'll bother broadcasting ATSC at
all, much less compliant ATSC, can make tuning the channels difficult.
As is true for the pcHDTV cards, recording a channel is easier than
trying to watch it as live TV. Set up a few one-minute manual
recordings to verify the card's operation, then choose one that works
well as a "starting channel."
Unlike the pcHDTV card, this card actually tunes to the starting
channel each time live TV starts, and myth will choke with a segfault
if it can't tune that properly. (When I compiled with debug
options, mythfrontend segfaulted out of gdb the moment it was run, so
I couldn't get a backtrace.) I had to try several channels before
finding one (PBS) that worked as a start channel, even though the
other channels worked for recording or when tuned to live after
starting.
These steps work for the V3.3 or V3.4 patch. Thanks!
