Hi

I'm a FreeBSD sparc64 user. I noticed that obsd now has
support for XVR-600 and similar graphical cards
(from http://www.openbsd.org/45.html):

# ifb(4), a driver for Sun Expert3D, Expert3D-Lite, XVR-500, XVR-600 and XVR-1200 framebuffers (accelerated).
# wildcatfb(4), an X driver for Sun Expert3D, Expert3D-Lite, XVR-500, XVR-600 and XVR-1200 framebuffers (unaccelerated).

FreeBSD doesn't support these cards.
I'm looking into the possibility
of porting ifb(4) or wildcatfb(4) drivers to fbsd.

However, I cannot find the sources for these drivers
at http://www.openbsd.org/cgi-bin/cvsweb/

Please advise

Also, could somebody comment on the feasibility of porting
eiher of these drivers to fbsd?

many thanks
