8-CURRENT Firewire

[Sean Bruno]

-CURRENT has some slightly different Firewire code in it than 6/7.  If
you have an opportunity to test it with your Firewire hard drives and
cameras I'd really appreciate it.

Stuff that's changed:
	multi-speed compatible devices will acutally work.
	     a 400/800 device is connected to a 400/800 compatible 
             firewire card via a 400 connection will work at 400
	fwcontrol understands multiple firewire cards as multiple 
	     buses now.  most commands now take a -u argument to
	     indicate the bus.

Please report to the -firewire if you get a chance to test.  It would
be great to get positive as well as negative results.
