About one year ago, radeonhd was the way to go: radeon for <=r400 and
radeonhd for >=r500. But the situation is (politically?) complex
nowadays. These new r500/r600 boards can be driven by "atombios" (some
sort of "high-level langage" from what I understand), or by low-level
routines (as usual). The radeonhd driver only uses the latter, while
radeon people would have preferred the former. So they wrote the former
in the radeon driver to see if it was better/easier than the radeonhd
code. So we now have 2 drivers with a different way to drive the same
boards. Now, it's getting even more hard to understand since radeonhd
recently got a atombios branch...

PS: Radeon people are reading this, so I have to say that I think/hope
radeon will win in the end :)
