Axel,
Are the open source "radeon" ATI drivers being kept up to date, or are
they a dead-end now? I looked at the list of supported chips on the front
page of the Wiki and all of the new chips are noticably absent from
the list. These drivers might be adequate for normal X, but clearly
they're falling far short on the OpenGL side of things, at least
with sophisticated apps like VMD. The list of hardware supported by the
ATI/AMD proprietary "fglrx" drivers seems much much more complete and
up-to-date.
Cheers,
John Stone
