fbsd 6.2 pf starts -- but not on boot

[snowcrash+freebsd]

hi,

i've fbsd 6.2R/p5, with pf compiled into a custom kernel.

on boot, pf is, apparently, not starting.

but, if i exec

	/etc/rc.d/pf start

immediately after boot to prompt is done, then all's OK.

the only related (?) messages -- error or otherwise -- i've found are
on startup.

any ideas/suggestions as to what might be the prob? and/or how to troubleshoot?

thanks!

for reference, from console output @ startup,
