Look at sys/dev/agp/agp_i810.c for supported intel devices.  The
missing /dev/agpgart means it didn't get identified as supported
hardware at probe time.

But you may be in luck.  It (pci id 0x2978086 matches your pciconf
listing) seems to be listed in the RELENG_7 version of this file, but
not RELENG_6.  You neglected to to mention what you are running, so
I'll guess 6.x

A few options... 

 - try a recent 7.x (support was added in July)
 - try to merge in the changes into your 6.x tree yourself
    (if successful, post here and/or send-pr the patch)
 - submit a PR requesting the mfc
