No creo que haya nada tan detallado como el /proc/cpuinfo de Linux. . Busca en sysctl hw y /var/run/dmesg.boot . La mayor parte de la información, como la velocidad de la CPU y los conjuntos de instrucciones, debería estar en alguna parte.
Esto es lo que veo (con algunos hw.* poco interesantes campos eliminados):
$ uname -sr
FreeBSD 4.10-RELEASE
$ grep -i cpu /var/run/dmesg.boot
CPU: Pentium III/Pentium III Xeon/Celeron (448.97-MHz 686-class CPU)
$ /sbin/sysctl hw
hw.machine: i386

hw.floatingpoint: 1
hw.machine_arch: i386

hw.an.an_dump: off
hw.an.an_cache_mode: dbm
hw.an.an_cache_mcastonly: 0
hw.an.an_cache_iponly: 1
hw.fxp_rnr: 0
hw.fxp_noflow: 0
hw.dc_quick: 1
hw.ste.rxsyncs: 0
hw.instruction_sse: 0

(Tenga en cuenta que en OpenBSD, la velocidad de la CPU se encuentra en hw.cpuspeed en lugar de en dmesg.)
Usa dmidecode comando:
# dmidecode -t processor -t cache
# dmidecode 3.0
Scanning /dev/mem for entry point.
SMBIOS 2.4 present.
