There is a bug here, whereby ifconfig(8) does not match the name
registered in the kernel by ed(4).  Erik Trulsson posted some patches
to fix this last month; search the archive for a thread titled
"strange problem with ed driver".  [1]

However, depending on the remainder of your kernel config, there could
be something additional going on here.  Note the discrepancy between the
dmesg (ed1) and the config file (ed0).  You might check whether you are
actually loading if_ed.ko in /boot/loader.conf.

[1] The following patch to ifconfig.c also solves this problem on my
system.  This is taken from v1.90 in HEAD and modifies the ifmaybeload()
function.  It does not break on any of the interfaces I use (ed xl lo),
but I don't really know what I'm doing - YMMV.
