DRI on an iBook2

Hi,
I see on the DRI project (http://dri.sourceforge.net/) page that the
ATI Rage128 Mobility chipset is supported by XFree86 DRI.  However,
I'm not having a whole lot of luck getting anything working on my
iBook2.  I notice that I *can* turn on the kernel option for the DRM
and select support for the ATI Rage128.  My question to this list
before I spend too much time beating my head against this is whether
or not DRM and/or DRI for the ATI chipsets are supported on LinuxPPC.

Thanks...
Ethan
