I'll venture a guess, no better.  

I bet GENERIC probes for one video device.  I would assume NetBSD would
happily handle a variety of devices willy-nilly, but you'd have to "nail
down" the configuration.  

vga1            at pci1 dev 0 function 0
vga2            at pci2 dev 4 function 0

approximately. Or even perhaps:

vga1            at pci? dev ? function ?
vga2            at pci? dev ? function ?

Worth a go, if your a custom kernel kinda guy.  Of course, I may be all
wet.  Even if that works, there would be other ramifications for, say,
wsdisplay, for example.  

HTH.
