yes, that's it:

mirka:~ # grep ^5: /proc/tty/driver/serial
5: uart:unknown port:1A8 irq:9
mirka:~ # setserial /dev/ttyS5 port 0x9800 irq 11 autoconfig
mirka:~ # grep ^5: /proc/tty/driver/serial
5: uart:16550A port:9800 irq:11 baud:9600 tx:0 rx:0 

So, adding this patch should help me. I can not test it right now, because
I do not have any serial device here at home, but will test it on monday.

Thank you for your help.

I can't make such predictions--my crystal ball is cloudy today.
