Jon,
  Ive had the same problems with the latest v4l snapshot locking the machine 
up, it does not matter whether I specify card=0x71 it still locks up, I just 
keep the v4l in the 2.6.10 kernel, that way when I modprobe bttv it 
autodetects my card. This will work ok if you have a newer red card with the 
eeprom on it, the older blue cards have no eeprom so you need to specify the 
card number but I think all dvbt cards have the eeprom on them. 

I run 2.6.10 with dvb-kernel cvs. Instead of runing make links in dvb-kernel I 
just copy the whole dvb directory over, it works ok.  I also run udev and had 
to put these rules in the udev rules file.

# DVB devices
KERNEL="dvb0.dvr*",        NAME="dvb/adapter0/dvr%n"
KERNEL="dvb0.demux*",      NAME="dvb/adapter0/demux%n"
KERNEL="dvb0.frontend*",   NAME="dvb/adapter0/frontend%n"
KERNEL="dvb0.audio*",      NAME="dvb/adapter0/audio%n"
KERNEL="dvb0.ca*",         NAME="dvb/adapter0/ca%n"
KERNEL="dvb0.osd*",        NAME="dvb/adapter0/osd%n"
KERNEL="dvb0.net*",        NAME="dvb/adapter0/net%n"
KERNEL="dvb0.video*",      NAME="dvb/adapter0/video%n"

If you run more than 1 card put it in again replacing 0 with 1 up to how many 
card you have. I have 4 twinhan dvbt cards so Ive put the above in 4 times.

I hope this helps.
