Networking troubles

Hello again,

OpenDarwin is now running on the laptop, however it did not detect the
"wired" network interface.  It's a Broadcom NetXtreme Gigabit chip
(BCM5705).  I looked at the HCL and it doesn't list it either way, working
or non-working.  After some poking around, I did notice that there's a
driver for BCM5701 (AppleBCM5701Ethernet.kext), but apparently the binary
is for PPC only.  However the AppleGMACEthernet binary appears to support
both PPC and x86.  Is this some kind of a universal network driver, like
the good old NE driver in Linux?  Anything I can do to force recognition
of my network card?  TIA.
