ati is package of drivers that supports radeon, r128, and other (older) 
ATI cards.  With ati installed, you can enter "ati" for the driver in 
the Device section of xorg.conf and it will pick the right driver.  Or 
you can just enter "radeon" and skip the autoselection.  The radeon 
driver supports the whole range of radeon cards including the HD series, 
although later chipsets aren't fully supported yet.  See radeon(4x) for 
a list of cards and types of acceleration supported.

radeonhd is a separate driver meant to support only radeon R500 (Radeon 
X1300) and above cards.

My impression is that the radeon driver is more mainstream and probably 
less experimental than radeonhd.  I'd try the radeon driver first, and 
only use radeonhd if it offers better support for your card.
