This got me curious so I took a look around at www.netbsd.org but, damm! -
not
a dang thing could I find about AGP. So I posted to the netbsd-help list and
got this

NetBSD-current has AGP support in general.

man agp(4) mentions following chipsets

           -   ALI M1541 host-to-AGP bridge
           -   AMD 751 and 761 host-to-AGP bridges
           -   Intel 82810, 82810-DC100, 82810E, and 82815 SVGA
controllers
           -   SiS 5591 host-to-AGP bridge
           -   VIA

Support for video cards is X's problem. An exception is DRI which is not
supported by NetBSD at the moment.

BTW, man agp(4) looks a little strange:

HISTORY
     The agp driver first appeared in FreeBSD 4.1.  It was adopted in
     NetBSD 1.6.

NetBSD 1.5.2                  September 11, 2001

I knew the bit about X but was rather surprised at the difficulty in finding
info on
AGP support. But there it is: Since the various free BSDs borrow stuff from
eachother
I suspect OpenBSD should have similar AGP support. Check you chipset.
