There should be no issues. The 6-pin connector is literally the 4-pin

connector signals (2 out, 2 in) with 2 power wires. There is no

difference in the IEEE-1394A specs for either connector and, in my

experience, the 4-pin has always worked for me.
The biggest issue with 1394 on Linux is the 1394 controller in the PC.

You might look around for evidence that your specific hardware (the

chip inside - not the laptop) is well supported. (I.e - TI is, others

vary) Stefan Richter in the 1394 user list is a great resource. lspci

is your friend.
Hope this helps,

Mark
