Although you say you are keen on the 3d part, it is the 2d side of things
where a little bit of effort can make the greatest difference at the moment.

The 2d acceleration for the radeon is fairly complete for the case where the
dri is disabled.  When enabled, however, the mmio interface is unavailable,
and dma-based acceleration routines must be used.  There are only a small
number of these written -- if you wanted to look at this, there is a fairly
shallow learning curve, good returns and a fair number of examples available.

Look at xc/programs/Xserver/hw/xfree86/drivers/ati/radeon* for more info
