I just pushed her changes to the xf86-video-ast driver to the two fox gates.
(Ignore the incorrect e-mail address on the fox-gate push - my process for
pulling changes from the Nevada gate to the fox gate assumes Sun NIS account
name and opensolaris.org account names are the same, and apparently some other
user has an opensolaris.org account with the same name as her Sun NIS account.
This will be fixed when we convert the Nevada gate from Teamware to Mercurial,
hopefully sometime this summer.)
It uses the newly defined common ioctl set from
PSARC 2009/224: visual_io.h ioctl definitions
instead of the model of each driver having it's own set of
driver-private ioctls used by previous SPARC fb drivers.
More details are in:

Unfortunately, the answer to this, for now at least, is no. It's derived
from code provided by ASpeed, and thus open sourcing needs to be worked out
with them. (They contributed the xf86-video-ast driver to X.Org, so they
have some experience there.)
