  I have a patch for this now.  It is located at
  http://people.freebsd.org/~rnoland/agp_i810-g33-g45.patch
  
  I need testers with g33 and g45 series chips.

Tested on 7.1 from today, previously this did not detect but now it does:

vgapci0: <VGA-compatible display> port 0xef98-0xef9f mem 0xf6c00000-0xf6ffffff,0xe0000000-0xefffffff 
irq 16 at device 2.0 on pci0
agp0: <Intel GM45 SVGA controller> on vgapci0
agp0: detected 32252k stolen memory
agp0: aperture size is 256M
agp0: AGP_I810_PGTBL_CTL: 00000001
agp0: AGP_I855_GCC1: 0x50
agp0: AGP_I915_MSAC: 0x00
agp0: Aperture resource size: 268435456 bytes

Thanks!  A few times I've seen X lock up and exit (I don't have the error
handy) but it has only been when I was using fluxbox.  I'm currently using
twm while gnome compiles but I kindof assume that problem has more to do
with the intel video driver rather than agp?
