 there's an s3c6410 one as well, somewhere around.

 the questions that should be asked are:

* are there any PCI / AGP / PCI-e ARM-based motherboards out there? (i
know of one or two PCI-based ones - certainly no AGP ones.  there
*does* however exist the OpenRD Ultimate which has a PCI-e connector,
and the increase in speed of ARM CPUs you *might* regret removing
them, as more modern ARM systems with PCI-e become more prevalent.)

* are there any vesa ones? (vesa is an x86 BIOS thing!)

* are there any sis USB ones?  well, it's USB so ... yes!

and there's one more.... darn it... displaylink - yep, that's the one.
 i'm not sure if sisusb contains a displaylink chip, i don't think it
does - it's something different.

 so i'd say definitely the vesa one could go, the sisusb one
definitely keep, fbdev definitely keep, but going through the list to
check which ones have PCI-e graphics cards? eurrrgh, good luck :)

 but, yeah, certainly if you say "is it PCI / AGP only, if so it's out
the window" then the really old ones where the companies have gone
bust or just stopped doing graphics could definitely go - there's a
list of obsolete graphics companies at wikipedia.

 good luck! :)
