I don't know apt, so I can't be of help there, but here are some 
comments that may help you once you get the modules installed (or might 
actually get your modules installed correctly if it's not a problem with

If you're running Linux 2.6.8, you really need to be running a version 
of ivtv > ~ ck100.  You could try ck100z (pretty stable, but might need 
patching for 2.6.8) or 108m (pretty stable, and fully 2.6.8-ready).

ivtv-0.1.10-pre2-ck80ish and above have autodetection support for the 
PVR-x50's.  Therefore, your modprobe.conf should be:

alias eth0 via-rhine
alias snd-card-0 snd-via82xx
install snd-via82xx /sbin/modprobe --ignore-install
snd-via82xx && /usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-via82xx { /usr/sbin/alsactl store > /dev/null 2>&1 || : ; }; 
/sbin/modprobe -r --ignore-remove snd-via82xx
alias usb-controller ehci-hcd
alias usb-controller1 uhci-hcd
# nvidia kernel module
alias char-major-195 nvidia-1_0-6111
# ivtv modules setup
alias char-major-81 videodev
alias char-major-81-0 ivtv

And nothing more.  (IOW, remove options ivtv, options saa7127, options 
msp3400, and install ivtv and ensure you use modprobe ivtv--*not* insmod 
commands--to load the modules.)

Also, if you can include the contents of your dmesg output or 
/var/log/messages between the lines

ivtv: ==================== START INIT IVTV ====================
ivtv: ====================  END INIT IVTV  ====================

It may give an indication why saa7127 is not loading.  Then again, when 
using autodetection, it might load correctly.
