3.1 and 3.0.2 have the options by default:
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/cobalt/conf/GENERIC#rev1.70.2.5.2.1
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/cobalt/conf/GENERIC#rev1.70.2.6

Note -current (and forthcomming 4.0) doesn't require this option
because sosend_loan() is disabled by default on all MIPS3 CPUs
in sys/arch/mips/mips/pmap.c.
