While looking for a way to port to IOData XGA-CF card to OpenBSD, I came across the Colorgraphic Voyager VGA. It seems like a real VGA output for the Zaurus...
So I checked if someone did some work for this on OpenBSD... Lo and behold! This is what I found... in the man pages!
CFXGA Man Page
Anyone has one of those cards and/or more information ?
