Sun gigabit 1/2 isn't supported afaik.
Sun gigaswift comes as bge and cassini. The bge versions probably work.
Intel em is only supported with a patch to the driver, and it will
still suck when using jumbo frames.
Syskonnect cards have solaris drivers, they probably work with freebsd.

None of these are really fast. On intel boxen the fast cpu makes up
somewhat for the crappy pci speed, and most of the onboard gigabit
is connected to a dedicated bus. On alpha, sparc, power, pa-risc in the
300-500 mhz range  you'll get about 300-400 mbit tops.

Intel boxen with 933-1133-2800 mhz, 64bit pci and em do about 800-900mbit.
