Hmmm, you might try XalphaNetBSD with the -noaccel option.  ISTR
that there were issues with the PWS433au and some of the accelerations
on some of these cards.

XdecNetBSD should already have rectangle copy acceleration which
I found to be the most important for my uses.  You probably don't
have to get all of the accelerations moved across to obtain reasonable

I did get XalphaNetBSD working with -zaphod, which is the predecessor
to Xinerama.  I think that there's an e-mail in the archives where
I describe how I did it (on this mailing list, many years ago.)
There were a couple of odd steps like mknod'ing /dev/ttyF0, etc.
