Thank you very much to both of you!

With that patch applied, the 5709S PHY is correctly attached
by brgphy and "seems to work".  I can't test it thoroughly
right now, though, because there is no cable attached to the
port ...  The machine is located in a customer's datacenter
in a different city and I'll have to ask someone to connect
the ports.  This is a little bit complicated in that company.  :-)

I will continue testing as soon as there's a physical link.
For now, this is what ifconfig says (bce0 only; bce1 is the
same):

 bce0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
 	options=1bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4>
 	capabilities=1bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4>
 	ether 00:21:5e:98:f6:6c
 	media: Ethernet autoselect (autoselect <half-duplex>)
 	status: no carrier
 	supported media:
 		media autoselect
 		media 1000baseSX mediaopt full-duplex
 		media none

Here's an excerpt from dmesg (verbose boot):

 bce0: <Broadcom NetXtreme II BCM5709 1000Base-SX (C0)> mem 0x92000000-0x93ffffff irq 30 at device 0.0 on pci16

And relevant parts from devinfo -rv:

Finally pciconf -lcv:
