i'd suggest you try latest 2.6.18 & perhaps combine it with dvb-v4l

most motherboard bioses allow you to configure explicit IRQs for different
PCI slots.  you should be able to find a combination where at least cx88
doesn't share its IRQ with any other device.

from personal experience, i've found in the past that i got cx88_abort
errors where something had (incorrectly) put an incorrect card=XX into
/etc/modprobe.conf - so the card wasn't being autodetected but instead was
being forced to something it wasn't.

you may want to verify that it is indeed autodetecting it and/or 'dmesg'
output shows that it _is_ the correct card.

of course, when i had the incorrect setting, tuning via tzap didn't work.
(well - it did - it would "lock on" but never actually tune to what you
asked... presumably just locked onto what it was previously set to..).
