Pro Gentoo, jinde to bude spíš jednodušší:

Do /etc/make.conf přidat VIDEO_CARDS="radeon", překompilovat systém. Přidají se balíčky radeontool a x11-drivers/xf86-video-ati. Pak přidáme ještě radeon-ucode firmware.

No výkon není právě oslňující, senzory také nevidím a KDE mi jede jen přes XRender. Ale funguje a proti onboard Intel je to posun. Věřím, že se vývoj nezastaví a bude to jen lepší.
