I cannot get FreeBSD 6.0 to recognize my serial port.  I am using the
ASUS K8V-X SE motherboard[1].  It only has serial port but dmesg
suggests there are two:

sio0: configured irq 4 not in bitmap of probed irqs 0
sio0: port may not be enabled
sio0: <16550A-compatible COM port> port 0x3f8-0x3ff irq 4 flags 0x10 on
acpi0
sio0: type 16550A
sio1: configured irq 3 not in bitmap of probed irqs 0
sio1: port may not be enabled

In the end I have no port:

$ ls -lh /dev/cua*
crw-rw----  1 uucp  dialer    0,  42 Mar 13 03:59 /dev/cuad0
crw-rw----  1 uucp  dialer    0,  43 Mar 13 03:59 /dev/cuad0.init
crw-rw----  1 uucp  dialer    0,  44 Mar 13 03:59 /dev/cuad0.lock

I have searched around and found similar problems but no solution is
apparent.  Any suggestions?
