You may have to define HorizSync and VertRefresh in the xorg.conf file.
I have a nexenta alpha 6 with updates that just comes up in 1280x800 by setting
the HorizSync value in the xorg.conf.

So you also need to define DefaultDepth in the xorg.conf file.

Since the virtual monitor doesn't specify EDID, it is unlikely to be able
to handle resolutions over the basic ones. I know that a while ago (maybe
18 months) I was able to get something like 1156x864 out of the adapter
with early versions of Solaris express.

Probably a combination of HorizSync/VertRefresh in the monitor section,
DefaultDepth in the Screen section, and a mode line, you might get what
you want.
