"the ultimate question" (plz dont post me 42)
yes...this is the ultimate question
is it going to be possible to install AMD/ATI drivers by clicking system>Administration>Hardware Drivers or do we need to download the source from git or some other bullshit place and compile it
and does the new (ubuntu 10.10) Maverick kernel supports the ATI Radeon 5xxx series
(if you ask witch version, know that is the 5830)
The Hardware Drivers mechanism will get you fglrx, not the open source drivers from git.
AFAIK the kernel driver in Maverick supports KMS on HD5xxx but needs a few extra patches for reliable hardware acceleration. You also need a new X driver anyways (and picking up a newer mesa driver wouldn't hurt).
they really should ad an button for xorg-edgers.
