Supplementary information:

My system also has a SCSI card with a couple of CD-ROMs on it, so that's
scbus0 and the firewire is scbus1.

I just tried removing the SCSI card and the firewire is zooming along (8MB
per second!)

This may or may not be a red herring - perhaps it's just the fact that I did
a reboot - but is it possible that something is wrongly assuming the device
to be on scbus0 when it's on scbus1 ?

Regards,

Bran.
