Is the ATI Radeon 7500 supported in XFree86 ?

Trying to determine if the ATI Radeon 7500 is supported by XFree86 is proving to be a real challenge. There are notes in various places about support for the 'radeon' and discussion on a variety of mailing lists about problems with non-ATI cards using the chipset, but nothing definitive ! The XFree86 release notes for 4.2.0 don't seem very clear, to me at least.

Obviously there are other vendors (Matrox G550 looks good), but the 7500 has DVI out and can be bought for less than 50ukp, which makes it seem like a good deal.
