agp_i810 not built on amd64?

I have a desktop with i945GMS builtin video.  It appears agp_i810.c is
not built on amd64, hence no support for agp.  This is on 6.x.

none0 at pci0:2:0: class=0x030000 card=0x31031565 chip=0x27728086 rev=0x02
    vendor     = 'Intel Corporation'
    device     = 'Integrated Graphics Controller'
    class      = display
    subclass   = VGA

sys/conf/files.i386:pci/agp_i810.c                     optional agp

$ ls /sys/amd64/compile/SMP/*agp*
/sys/amd64/compile/SMP/agp.o            /sys/amd64/compile/SMP/agp_if.h
/sys/amd64/compile/SMP/agp_amd64.o      /sys/amd64/compile/SMP/agp_if.o
/sys/amd64/compile/SMP/agp_if.c         /sys/amd64/compile/SMP/agp_intel.o

Is there any reason not to use i810 on amd64?  A quick glance through
doesn't show it doing anything 32-bit specific.  On -current, it appears
to be enabled for amd64.  It appears this MFC never happened:

Include agp_i810.c in amd64 AGP builds to get support for the Intel 915
Express chipsets.
