If you are using recent sys/netinet6/in6_ifattach.c, you should have
no problem with that. When no MAC address is available in the system
the kernel will generate IPv6 interface identifier from
as a last resort. you will get kernel printf() like this when you do
gifconfig (visible via dmesg):

Jon, what kind of kernel printf did you get when you did gifconfig?
