I decided to drop the iftab thing and replace it with udev rules. The=20
following rules do the expected renaming:

KERNEL=3D=3D"eth*", SYSFS{address}=3D=3D"00:13:77:04:a7:77", NAME=3D"eth0"
KERNEL=3D=3D"eth*", SYSFS{address}=3D=3D"00:00:f0:41:20:07:e8:49", SYSFS{ty=
pe}=3D=3D"24",=20
NAME=3D"fw0"
KERNEL=3D=3D"eth*", SYSFS{address}=3D=3D"00:13:02:0f:56:a2", SYSFS{type}=3D=
=3D"1",=20
NAME=3D"wlan0"

lsmod shows a use count of 4294967295 (2^32 - 1), no oopses or the like. Th=
