The only other driver I can use would be this Nouveau one I heard about on freebsd-x11, but that would involve another system upgrade, and it is currently marked as broken.  The Vesa driver doesn't work on my cards, and nvidia won't support amd64...

The issue is in fact the switch to libpciaccess, along with a lot of
changes to Xserver.  The issue is due to legacy vga handling.  The issue
is being discussed a bit more lately, but no resolution is at hand.
Most modern cards have a way to deal with this, but it isn't a
generalized solution.  So, for right now, multiple cards generally don't
work, for linux, solaris or us...
