Firewire problems

[Julio Merino <jmmv%julipedia.org@localhost>]

Hello,

I had been running NetBSD 5.1 on a Mac Mini G4 1.2GHz with an external
fw400 hard disk without issues.  I have recently updated the machine
to -current (5.99.49, GENERIC) and the firewire port does not work any
more.

Attaching below the relevant messages from dmesg.  Any ideas?

Thanks!
