Atualização das 19:50h: (rsrs)
-----------------------

Servidores rodando 8.2-PRERELEASE (tag RELENG_8 no cvsup, tb conhecido como
8-STABLE):

# uname -a
FreeBSD border01 8.2-PRERELEASE FreeBSD 8.2-PRERELEASE #0: Tue Jan 25
17:19:08 BRST 2011
     root em border01.scr:/usr/obj/usr/src/sys/BORDER-RTR  amd64


=> Finalmente consegui usar o Jumbo Frames!
=> Os kernel panic pararam de ocorrer desde que bootei o 8.2-PRERELEASE.

Porém, como nem tudo é perfeito...

Lendo o link do nosso amigo Danilo Baio, descobri que aumentando um pouco os
parâmetros
'kern.ipc.nmbclusters' e 'kern.ipc.nmbjumbo9' o problema para:
