Working fine here... the biggest problem known to me is performance,
working on fixing that, see my recent post to the dri-devel list.

The AGP options tend to work fine on PPC Macs, and when they don't work,
they usually just result in lockups. It's true that page flipping can
cause issues with compiz, but those can usually be worked around by
rotating the cube or running glxinfo.

These might indeed work around the AIGLX GLX_EXT_tfp performance issues
somewhat.
