Your lspci looks fine, but it really means nothing. It doesn't tell us what
went wrong.
Providing a good chunk of your dmesg may be better as the lspci results seem
to show things as fine.

Also, did you do an inplace upgrade or a backup of your database and then
restore it into the newly upgraded system?
I recently ran into an issue moving from 2.6.22 to 2.6.30 where the drivers
were installed fine for my pvr-500 but myth did not see them. Going into
mythtv-setup and they were there and setup right. But there was a gap in my
recorder list in status. Deleting the cards in mythtv-setup and recreating
them resolved it, but it was weird.
So, if you are still using your old database, try deleting your cards and
recreating them.
