Well googling for "lomount" yields a lot of people looking
for it, and this site:

http://www.mail-archive.com/gentoo-user@xxxxxxxxxxxxxxxx/msg70745.html

says:

  "According to this very useful site:

   http://www.portagefilelist.de/index.php/Special:PFLQuery

   the only package that provides lomount is xen. Which seems odd."

Since it is very helpful for recovering from an update to
an in-guest kernel (which is often useful in xen development
but probably also periodically useful to support xen distros), I'd
propose that CONFIG_LOMOUNT get turned on by default in Config.mk.
If we get complaints, it's easy enough to turn it back off later.
