I have been doing this for a while, now.  What I have done is
apt-get source mythtv.

this brings down the source packages that Christian sets up.
Then I have to modify mythtv-0.19/debian/rules to point to my 
linux-headers-2.6.16-1-k7.
I also have to modify settings.pro and add
QMAKE_PROJECT_DEPTH This was in a dpatch file in 0.18, and somewhere/someway it got dropped 
from 0.19.  I have asked Christian about it, but he has not responded. 
Without that line, I get failures on setup.xml, and stuff strewn around 
in wierd directories on my box.
I do a 'dch -i' to increment the versions, and to put in some comments, 
so I remember the next time what I had to do.

Once I do those, I can issue a
debuild
and wait for failures.  If you get dependency problems, just apt-get the 
development libraries/files that you need.

Once the debuild is successful, you can dpkg -i all the debs you just 
built and you should be able to see your HD3000 card.

I do not believe it's an issue with Christian's build system.  Remember, 
Debian stable/sarge is on 2.6.8-3 kernel, and apparently the v4l/dvb 
modules have changed in the later kernels, so Christian's stuff does not 
have the changes required for the later kernels.  The only way to get 
that as of right now is to build the packages for yourself.
