Or, actually, you could just give in and use a different dhcp
client... one more forgiving of less RFC compliant servers.  Just
winging an admittedly untested idea... try "busybox udhcpc" and see if
it gives you the right IP... and if so, try emerging net-misc/udhcp
(different from BB's built in, but it's worked in all the same places
as BB's has for me, which includes some very cheap routers) and
setting your conf.d/net to use it over other clients. ( modules=(
"udhcpc" ) )
