yes, I know this page (google rules :-).
Anyways, I thought that FIR and SIR are two different infrared protocols
and devices which work on one don't work on the other. Now I understand
what it means. So, I play with SIR now (I need only 9600bps dialout, so
speed really doesn't matter to me yet).

ok, I reconfigured irda-common, selected serial, /dev/ttyS1 and for
dongle none. Now the messages from kernel are:

there's no such setting in my bios, I can only set IRQ, I/O Port and DMA
channel under Infrared setting. It is correct:
ttyS01 at 0x02f8 (irq = 3) is a 16550A

hm..... That's all I can get from irdadump, sometimes after
initialization. (the phone's infraport was turned off at this time, I
turned it on later and irdadump wrote nothing about it).
