missing serial devices on NetraX1

[Honza Dusak]

Yesterday I installed FreeBSD-5.1BETA on NetraX1 and I wanted
to use the serial B port as a network interface ( slattach ) .
But I cannot find any notice about serial drivers in the dmesg
output and neither there is no ttyb ( or cuaa* )  device at 
/dev directory . 

Please, can anybody advise what can be missing ?
