Hi Nick,
Could you post the output of
lspci -vvv -nn
for the device in question - you'll also need to give the -s argument,
eg -s 02:00.0
or whatever.
This is so it is clear what chips your example of the card is using -
a given card may be implemented with different chipsets over time
depending on how organised the manufacturer is.
Some kernel output similar to that shown on the wiki page, showing
what happens at boot time, may be useful as well.
I have this card, and it is working reasonably well with recent
media_build code:
$ sudo lspci -vvv -nn -s 04:00.0
