Hi Ulrich,

It appears that I have the same card as you, but I performed the
simple test anyways (kernel recompile will have to wait until my ~5
hour computation finishes).  The link up message appears
automatically, but the link down message does not appear until I issue
an ``ifconfig" command.

pciconf -lv:
bfe0_at_pci2:0:0:  class=0x020000 card=0x81271028 chip=0x440114e4 rev=0x01 hdr=0x00
    vendor   = 'Broadcom Corporation'
    device   = 'BCM4401 10/100 Integrated Ethernet Controller'
    class    = network
    subclass = ethernet

I will hopefully give the patch a try in the next couple of days.
