I think eth0 is your FireWire port (IEEE 1394).

You did the right thing already (taking eth0 down). Now you can
install Gentoo and unless you configure support for Ethernet over
FireWire (or something similar) in your kernel you shouldn't have any
problem.

That was my experience anyway (with a different Asus board, but the
same behavior).

Louis is right, you can also disable this behavior by adding
"nofirewire" at the bootloader line that calls the kernel.

  Thanks Daniel and Louis.  With "nofirewire" the boot messages showed 2
eth devices, but the real ethernet chip now comes up as eth0, which is
what I wanted.

You can use udev rules to ensure your network interfaces are correctly
named, which saves disabling anything. On the other hand, if you will
never use Firewire networking, you could simply remove the option from
your kernel.

The udev rules I use to ensure my wired, wireless and Firewire interfaces
are named i that order are

KERNEL=="eth*", SYSFS{address}=="00:0d:93:3c:76:26", NAME:="eth0"
KERNEL=="eth*", SYSFS{address}=="00:0d:93:ef:f2:c0", NAME:="eth1"
KERNEL=="eth*", SYSFS{address}=="00:0d:93:ff:fe:3c:76:26", NAME:="eth2"

Those are the MAC addresses of the interfaces.
