This is my mistake. Using 9.2's crypto.inc seem to result evil
CPU lock up when accepting ssh connection and STOP+A is needed
to recover. So please ****do not try**** only changes of bn.inc
above.

Now trying crypto.inc as following:
----8<--------8<----
.PATH.S: ${.PARSEDIR}
.PATH.c: ${.PARSEDIR}
CPUID = yes
CPUID_SRCS += sparccpuid.S sparcv9cap.c
CPPFLAGS += -DOPENSSL_CPUID_OBJ

.if ${MACHINE} == "sparc64"
CPUID_SRCS += sparcv9-mont.S sparcv9a-mont.S 
CPUID_SRCS += sparct4-mont.S vis3-mont.S
#CPPFLAGS += -DOPENSSL_BN_ASM_MONT
AFLAGS.sparcv9-mont.S+= -Wa,-Av9
AFLAGS.sparcv9a-mont.S+= -Wa,-Av9a
AFLAGS.sparct4-mont.S+= -Wa,-Av9a
AFLAGS.vis3-mont.S+= -Wa,-Av9a
.endif

.include "../../crypto.inc"
----8<--------8<----

Note that in 9.1, sparccap.c is used instead of sparcv9cap.c. 
Result of above crypto.inc and sparccap.c/sparcv9cap.c will be
reported later.
