Debain package for X-free86-4.2 or 4.3 ?

[Al Dykes <adykes@panix.com>]

I'm setting to Debian on a laptop. It has a Radeon Mobility
video system that needs a late version of xfree86, at last
4.2.0.  Can someone point me to the name of an apt package
and the server it's on. Thanks.

My second choice would be a tarball I can download,
with X setup for dummies ;-)

thanks
