Do you know how to update the table in the driver, rebuild/install
kernel and check?

I'm afraid not. I grepped for the hex value reported on the one that works
(chip=0x16b414e4), but I couldn't find it in its entirety, 16b4, or 14e4. So I
don't know what to add :-(
I don't have any problem with rebuilding and installing a new kernel, though.
14e4 is the ID for Broadcom
16b4 is the ID for BCM57765, a NetXtreme Desktop/Mobile chip
http://www.broadcom.com/support/ethernet_nic/determine_driver.php has a list
of the BCM PCI ID values
There is a (frequently incomplete) database of user reported PCI values at
http://www.pcidatabase.com. It has the BCM ID (14e4), but not your chip
Linux uses the tg3 driver for that chipset apparently, but I think thats
a general dumping ground for a lot of Broadcom products. Not sure what the
appropriate FreeBSD driver to add the ID code to would be.

Sorry, I should have been more clear. I grepped for those values in
/usr/src/sys/dev/bge/*, since that's the driver that's used on the older minis.
I assume that's where the table is that Alfred mentioned; I just don't know what
to add to it.
Here's a cool trick you can do.
1) make a backup of your /boot/kernel directory:
mv /boot/kernel /boot/kernel.good
(now you can boot to a known good kernel if you blow things up)
2) hack a few drivers to add the PCI id.
3) now build a kernel WITHOUT most of the nic drivers.
4) reboot with this kernel
5) try loading/unloading the various drivers you suspect will be
compatible until it either works or you get tired. :)
Eventually you'll find the change that works.
Go look at commit logs to see how others have added PCI ids to the
drivers. It's usually in a table or under a simple "if" statement.
It honestly won't take you that long, probably a few hours of head
scratching.
