Hi,
I know this is a very old thread, but wanted to mention that I just tried the Win7 32 bit driver (posted by TekWiz2010 above) on a really old machine I had given to my son, and it worked perfectly w the generic Radeon 7000 card, and can now support 2/dual monitors.
We had almost given up on being able to do that, until I found TekWiz's post, and I actually just registered here to say thanks, but maybe this'll help someone....
Jim
