To the best of my knowledge, the only driver that supports this is
Nvidia's proprietary driver.  I don't know if ATI's fglrx driver
supports it or not, but someone else might be able to comment.

Yes, it is quite upsetting and frustrating to many users, and also to

I'm not sure how closely any of the hardware vendors track Fedora
development with their drivers, however traditionally they seem to
release drivers a month or so after a new OS release, which claims
to work with the new OS release.  I'd recommend reading the
documentation in the driver download to see what they claim to
support in any given driver release, and if FC5 isn't listed, wait
until it is listed.

Otherwise, it's probably just a lot of headaches ;)
