Tainted kernel. It would be better if you can produce the oops without the
taintware^Wproprietary module; the fewer malign influences, the better :-)

No need to reinstall. Use your live CD, mount your root partition, append
"blacklist tuner_xc2028" to etc/modprobe.d/blacklist (relative to the mount
point). You'll need to modprobe the module manually after rebooting, this
time from HD; testing should, however, be easier now. I doubt that it'll
remove any need for reboots, though; that's just a hazard of driver
development and debugging.

Incidentally, try this:

$ cd /path/to/v4l-dvb
$ gdb v4l/tuner_xc2028.ko
(gdb) list *(generic_set_freq + 0x593)
(gdb) edit *(generic_set_freq + 0x593)
