radeonhd is an Xorg driver for AMD GPG (ATI) R5xx/R6xx/R7xx
based video cards.
At the time of this writing, radeonhd has the following lim-
itations:
o Support for hardware-based 2D acceleration and Xvideo
needs more testing on R6xx and R7xx based cards.
o No TV and Component connector support so far.
o After using the fglrx driver, radeonhd might fail to work
properly. This combination is not and probably will never
be supported. A reboot fixes problems in most cases,
sometimes a powercycle is necessary. Unloading the kernel
module is typically not enough.
