What /proc file is the img command pulling the /dev/hda capacity from. At
first glance I thought it was /proc/partitions, but now it's not looking
as though that is it.

It isn't - strace shows the follow:
open("/dev/hda", O_RDWR|0x8000)
ioctl(5, BLKGETSIZE, 0xbfffea8c)
ioctl(5, 0x303, 0x8095fac)
ioctl(5, HDIO_GETGEO, 0x8095fac)
which presumably means it's GETing the GEOmetry of the drive with
those ioctls.
