Along similar ines of other replies I don't think you need any drivers
for the Radeon series of cards - and I've never heard of a control panel for
OSX - do you mean ATI Displays prefs pane?
The last rom update for the 7000 was January 2005 - maybe you should try
running that - it's available from their site just search for ati drivers
and it will take you to the drivers page - there are two options only to
download - the ATI Displays and the Jan 2005 rom update.
If your card is agp it's probably a flashed card as I think the Radeon
7000 mac edition was pci - and this is something you REALLY need to know
before applying the rom update - because if it is a flashed card and has not
had the full mac rom chip fitted the rom update will try to write 128k of
data to a 64k chip and bugger the card. Let me know if you need to know
more...
