That address is normally used by ttyS1. Just irattach to ttyS1, and don't
fiddle with setserial.

You still need the irattach. The irnine device here matches the number for
my ircommnew0 - that's not a real physical device, but IrCOMM. It's piped
through the irda, which you still need to activate using irattach.

No idea here. ircomm0 on my machine points to older device numbers; the
new ones, ircommnew0 and friends, point to the 161 range, so your irnine
would work.

That's a very unusual parallel port to take DMA 7. An ECP port normally
grabs IRQ 7 and DMA 3.

You can still use the slower speeds with a FIR driver. It's automatic. I
don't know what chipset you have, try lspci -v, pnpdump and findchip
(don't know quite where to get findchip from).
