Yes, you must use ATI's fglrx drivers. The open source drivers won't
work for HD, regardless of how fast your CPU is.

Typically, with your kernel source available where it should be, just
run the ati-installer downloaded from ATI's website. You can try using
your distro's package, but I've actually had better luck with ATI's on
both gentoo and SuSE, although I have gotten them to work as well.

ATI no longer includes the 'fglrxconfig' tool to help set up your
xorg.conf, but instead they have 'aticonfig'. It's not as automated, but
allows for better control.

Here's pieces from my xorg.conf of just the relevant sections:
