PGX24 (ATI Rage Pro) and m64 (ATI Rage-XL/Mach64) have enough
hardware differences that it warranted separate Solaris drivers.
They are not the same.

The biggest issue with using Xorg drivers is some of them rely on
the x86 VBIOS on the card to do the low level initialization and setup.
The FCode on the Sun pgx24 and m64 does low level initialization but it
may setup the card in a mode unexpected by the Xorg driver.  A lot
of testing needs to be done to verify the behavior of Xorg drivers
on SPARC.
