Booting with 8250.nr_uarts=1 makes smsc-ircc2 module load:

Even irdadump shows there's other IrDA device is around (nokia 6233):

But whenever I try to open minicom (or kppp) using /dev/ircomm0, it hangs, and
irdadump shows the following:

Meanwhile nokia phone shows IR port icon blinking (i.e. no connection
established, searching) while this icon should stop blink and stay on at this
stage.
PS: Ervin, neither I do have those modules. 8250 code is in kernel, try it and
post your experience here too.
