I don't have the s4881 motherboard, but I would be
surprized if FreeBSD did not work on it. 

My research group recent purchased a small hyperblade
cluster from Appro.com.  The system has 6 nodes that
are based on the s2881 motherboard with 2 dual-core
2.4 GHz opteron, 16 GB of memory, and 233 GB hard drives.
MPICH2 and gfortran appear to work quite nicely on 
the cluster.  The cluster includes a GigE switch, which
I hope to replace with infiniband or myrinet in the

I have no experience with the daughter board you mentioned.
