The board in question is grantsdale (aka 915G):

My understanding is that, this driver needs to be enhanced to support the
915G chipset:

#define CHIP_I810 0     /* i810/i815 */
#define CHIP_I830 1     /* 830M/845G */
#define CHIP_I855 2     /* 852GM/855GM/865G */

Also, agp_810.c may be a little bit of a misnomer for the file, given that
it seems to support other chipsets.

This is true of the xorg i810_drv.o as well. Even though the name suggests
only i810, it really supports a range of chipsets including the 915G:
