So gentoo does use the numerical runlevels (because that's what init
uses) as well as the gentoo runlevels you've shown. It looks like it
just maps the numbers to the names in inittab;

l0:0:wait:/sbin/rc shutdown
l0s:0:wait:/sbin/halt -dhp
l1:1:wait:/sbin/rc single
l2:2:wait:/sbin/rc nonetwork
l3:3:wait:/sbin/rc default
l4:4:wait:/sbin/rc default
l5:5:wait:/sbin/rc default
l6:6:wait:/sbin/rc reboot
l6r:6:wait:/sbin/reboot -dk

so, i guess this means i should point l4 to a custom runlevel in
/etc/runlevels that is the same as default with the exception that xdm
is removed... I'm assuming the linux kernel wont understand the gentoo
named runlevels, and therefore using those names in grub wouldnt work.
