Please send the dmesg output (or lines from /var/log/messages) between 
the lines

108m might be more stable for you.  100z is probably more stable still 
if you can find it for 2.6.8.1 (because it required some patching for 
that kernel).

Please use the following for your modprobe.conf:

alias eth0 8139too
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

Only.  IOW, remove the lines:

install ivtv /sbin/modprobe msp3400 saa7115 tuner v4l1-compat;
/sbin/modprobe --ignore-install ivtv
options ivtv ivtv_debug=1 tuner=2
options msp3400 once=0 simpler=1 simple=0
