enable IPFIREWALL_DEFAULT_TO_ACCEPT for GENERIC kernel

[subbsd]

Hello maillist,

Whether there is a way for booting GENERIC kernel with 
ipfw_load="YES"

and

65535 allow ip from any to any

rules without recompile kernel with options IPFIREWALL_DEFAULT_TO_ACCEPT ?

This is single options who force me customize my own kernel with freebsd-
update.

Thanks!
