Oh yeah.  I forgot about that.  I ran into that problem long time ago
so I have always used video cards with dual outputs so I don't have to
worry about it.  I think i'm on my 4th card now.  But other than
possibly a restriction that all screens operate at the same color
depth, i believe xinerama has supported different video cards and
different resolutions for quite some time now.

A google search on xinerama gave plenty of hits.  Heck, there's even a
wikipedia entry now.

Oh, this site has a multihead how-to dated 2002
