FreeBSD XXX 8.1-STABLE FreeBSD 8.1-STABLE #2: Wed Aug 25 10:38:50 CEST
2010     root at XXX:/usr/obj/usr/src/sys/XXX  amd64

Date of source is Aug 17 14:09 CEST 2010. It happend with 8.1-RELEASE
too, I can go back to RELEASE or any SVN revision you would like, if it
is helping in any way.

There is an shared IPMI interface on em0, but the interface is not used
by FreeBSD. em1 is used by four VLANs. Polling is only in the
Kernelconfig, not activated on the devices.
