        src/sys/dev/pci: agp_i810.c

Log Message:
Don't trust the MSAC register after all; use the GMADR BAR size.

Previously this read the MSAC register from the wrong PCI device.
Experiments reveal that even on the right PCI device, per the
datasheet, the GMADR BAR size is correct.

Not clear that the driver has any business reading any of these GMCH
registers to discern the aperture size -- seems to me they are meant
to be written by the BIOS to determine the GMADR BAR size.  Lacking a
variety of hardware to test, though, I'll leave this as is for now...
