Have *you* disabled Firewire?

I'm seeing evidence that the Firewire stack has been problematic for a
small, but growing set of users out there.  I see from a perusal of the
mailing lists, that some users are disabling their Firewire stack after
they cannot boot or install FreeBSD.  This usually is due to a panic
preceded by the message:"
	"run_interrupt_driven_hooks - waiting for xpt_config"

This log message was added in the past to provide a diagnostic
indication of a failure.  

If you are one of these folks who have disabled their Firewire driver,
please let me know.  Also get me the following:
	Full boot dmesg output (bootverbose)
	Can you load "firewire"?(in kernel? after boot via module?)
	Can you load "sbp"?(in kernel? after boot via module?)
	*anything* else you might thing is relevant?
