In fact this isn't a problem at all. A Gentoo admin only have to set:
RC_NET_STRICT_CHECKING="lo"
in /etc/conf.d/rc

the config file states:
# RC_NET_STRICT_CHECKING allows some flexibility with the 'net' service.
# The following values are allowed:
#  none  - The 'net' service is always considered up.
#  no    - This basically means that at least one net.* service besides 
net.lo
#          must be up.  This can be used by notebook users that have a 
wifi and
#          a static nic, and only wants one up at any given time to have the
#          'net' service seen as up.
#  lo    - This is the same as the 'no' option, but net.lo is also counted.
#          This should be useful to people that do not care about any 
specific
#          interface being up at boot.
#  yes   - For this ALL network interfaces MUST be up for the 'net' 
service to
#          be considered up.

Gentoo scripts are far more flexible than you would believe at first 
glance :-) Just look at the /etc/conf.d/<subsystem>. In this case we are 
speaking of the "rc" script which does the dependency resolution.
