Just a note on the three cards, I assume you're talking about PVR 
(hardware mpeg encoders) style of cards???   If you are, I would caution 
you about that.  I attempted to run three PVR-250MCEs with a 2.6.7 
kernel, ivtv-0.1.10-pre2-ck97k and NVIDIA*run.pkg proprietary drivers 
for a GeForce4 440MX video card.  It would not work, the nvidia driver / 
ivtv driver would collide and the video card would not work properly (X 
refused to find usable screens).

I could run two PVR250MCE cards, but not three.  Yes, I did try serveral 
nvidia drivers including the "NVIDIA-Linux-x86-1.0-4363.run" to no 
avail.  The problem doesn't seem to appear to be an NVIDIA issue, as I 
was able to run three cards in my 2.4.x system.
