kern/113785: [firewire] dropouts when playing DV on firewire
Still cannot get VIA VT6307 controller to go into "non CYCLEMASTER 
No workaround.

kern/118093: firewire bus reset hogs CPU, causing data to be lost
Firewire driver must be locking out other drivers (e.g. ethernet)
when it shouldn't.  I still think it is a locking/mutex type problem.
Why does the firewire driver need to lock out Ethernet?
The new rs-232 driver in 8.0 didn't fix this.  Workaround: change
printfs to log(9) so that it doesn't print to console.
