Ok, with a new card that may be compatible, the driver may not recognize 
it by the numbers.

ATI Technologies Inc Unknown

from your lspci may be an indication of this type of problem.

In the case where a driver will work with a device newer than the system device catalog (the hwdata rpm) you can specify the device ID on the modprobe command line and in the /etc/modprobe.conf.

The descriptions of the device on each line of lspci comes from the hardware database, /usr/share/hwdata/pci.ids (from the hwdata rpm).  If the number does not match, it prints the number instead of the description.  In your case: 'ATI Technologies Inc Unknown device 4d52' means that the vendor ID was found, but NOT the device ID (45d2).  Try lspci -n to see just the numbers.

So, you have two things to try.

Simply edit the  /usr/share/hwdata/pci.ids file and add a line that will work.  The confusing part here for me is the ATI description and your description don't match.  The TV-Wonder series is by Brooktree, not ATI.

But in any case, that file will give you lots of clues to google for.

And, a 'yum update hwdata' may be all it takes to fix it in the first place.

Good luck.
