Polling support for hme(4) is one of item in my TODO list. It's not
complex and easy to add polling support code but I have no idea
polling on SMP really helps.

At present em(4) does not work on sparc64.
See http://people.freebsd.org/~yongari/em.patch.0419
It's old patch but you may see the point.

There is also bge(4) patch(http://people.freebsd.org/~yongari/bge.patch.0908).
Due to recent bge(4) changes it wouldn't apply cleanly but I think you
can patch the driver manually.
