I finally got both of my video cards working in FreeBSD. I had to switch the boot order to have the PCI card init'd first. Now I'll have to swap my cables around when I play games in Windows, but since that won't happen for a while, big deal.
I've got an ancient-seeming ELSA Gloria Synergy PCI card w/8MB (glint driver) and an ATI XPert@something-or-other w/8MB (Mach64 driver). XFree86-4.2 is putting out two lovely 1280x1024 screens at 75Hz apiece.
In other news, I was working with Unfurl to get freenet6 to work on toxic with unfurl, but no luck.
