Make sure your old laptop has a OHCI chip. I heard some old sony laptop
has a controller other than OHCI.
The easiest way to do aync. request is using /dev/fwmem0.
There are some examples in /sys/dev/firewire/00REAME using with ps,
dmesg and so on.
(sysctl node has changeg to 'hw.firewire.fwmem.eui64_{hi,lo})
To test write request, dcons/fwchat is an interesting application.
