description:
Divide GIG by 512 (DEV_BLKSIZE) so we don't overflow 32 bit u_long
when multiplying by 128 (in 32 bits, 128 * GIG == 0)

Should fix i386 build )and other 32 bit ports).

An alternative would be to use ULL rather than UL for the numbers,
but that would mean needlessly doing 64 bit arith for data that is
resticted to 32 bit results anyway.
