Sure... The problem is related to the way FreeBSD determines memory by
reading the # of KB from the BIOS location. This is only 2 bytes long
and so the 65536 KB limitation. You need to override this number by an
explicit MAXMEM setting in you kernel config file. Eg.
options "MAXMEM=81920" # 80MB Ram in 1KB chunks
