I had a similar problem with my D600, but the ATI setup program
wasn't kind enough to tell me which .inf file it was looking at,
so I had to dig. After reading several .inf and .ini files, I
thought I had determined which one to try, and went into windows
manual driver install with the "have disk" option, selected the
..inf file, and started trying drivers whose descriptions were
the closest match. Three of the entries had identical names
(Radeon 9000), the first one didn't work, but the second did.
Something similar may work for you.
