Just for now I am using:
> uname -a
FreeBSD wep4035 8.0-CURRENT FreeBSD 8.0-CURRENT #0: Fri Mar  6 18:47:22 CET 2009     root_at_wep4035:/usr/obj/usr/src/sys/GENERIC  amd64
> uptime 
 9:10PM  up 5 days,  5:20, 4 users, load averages: 0.02, 0.01, 0.00

The system is working but I'm not sure there is no corruption...

FYI,
Alexey.
