 I recently bought a Dell R420 which had BCM 5720 as the LOM.  The
 output of pciconf was the following:

bge0 at pci0:2:0:0:        class=0x020000 card=0x04f81028 chip=0x165f14e4 rev=0x00 hdr=0x00
    vendor     = 'Broadcom Corporation'
    device     = 'NetXtreme BCM5720 Gigabit Ethernet PCIe'
    class      = network
    subclass   = ethernet

 On 9.1-PRERELEASE as of Jul 23, it was recognized but did not work
 properly first (the link-status went back and forth between up and
 down).  However, after setting dev.bge.0.msi=0 it worked.  I am not
 sure of whether it had decent communication speed or not, but I saw
 it worked with 50MB/s or so at least.

 IPMI over LAN did not work even if hw.bge.allow_asf was set to 1.
