This is what I use in my kernel config
options "COM_MULTIPORT" #Multiport support in sys/isa/sio.c
#device sio9 at isa? port 0x2b8 tty irq 5 flags 0x901 vector siointr
#device sio8 at isa? port 0x2b0 tty flags 0x901 vector siointr
#device sio7 at isa? port 0x2a8 tty flags 0x901 vector siointr
#device sio6 at isa? port 0x2a0 tty flags 0x901 vector siointr
device sio5 at isa? port 0x1b8 tty irq 9 flags 0x501 vector siointr
device sio4 at isa? port 0x1b0 tty flags 0x501 vector siointr
device sio3 at isa? port 0x1a8 tty flags 0x501 vector siointr
device sio2 at isa? port 0x1a0 tty flags 0x501 vector siointr
device sio1 at isa? port "IO_COM2" tty irq 3 vector siointr
device sio0 at isa? port "IO_COM1" tty irq 4 vector siointr
This is one 4 port AST compatible card on irq 2 aka 9 and the two
standard serial ports com1 and com2.

My AST clone has only two IO address spaces low as above and a high space
with 0x2a0, 0x2a8, 0x2b0 and 0x2b8. If your cards has more than this
two it is possible as long as there are 4 irq lines available.
