I used the on-board serial port as a known working control (after getting it to work with the other onboard serial port) to try and connect over to one of the Syba card ports (using Cutecom & getty). The lines light up, but there's nothing getting sent from the 8-port as far as I can see.

Oh crap... I missed this fscking "Disabling IRQ #17" line in your dmesg.
Can you try with firewire controller disabled somehow ?

Ah, I forgot to make note of that. I did actually turn off Firewire in the BIOS. Assuming that worked (and it looks like it did) the following section probably contains the relevant bits. Still getting the IRQ 17 error.
