Any chance of trying the card in a) another system (non-64bit) and b)
using a non-udev based distro - perhaps FC2 to make syre the card is
fully functional.

The lock-up could be a serious IRQ problem causing a hard-lock during
boot - can you see whether any other devices are sharing the same IRQ
as the PVR card after the BIOS has posted. Sometimes, conflicts with
graphics cards getting the same IRQ can cause system instability such
as this (I've seen similar things under Wintel - removing the
'problem' card lets a system boot normally, replacing the card gives
the hang)

HTH a little,
