What do you mean with 'no' serial ports are available?
Your dmesg output says that at least one port is available:

pcmcia0: CIS checksum failed
pcmcia0: CIS version PC Card Standard 5.0
pcmcia0: CIS info: Socket, Dual I/O HS Card Win CE Rev 2.1(Legacy)
pcmcia0: Manufacturer code 0x104, product 0xa1
[..]
com2 at pcmcia0 function 0: <Socket, Dual I/O HS Card Win CE Rev 2.1(Legacy)>
com2: ns16550a, working fifo

Btw I think you don't have the 'normal' rs232 card. There are two type of cards,
one is the normal one and the other is a highspeed card.

You could try to add the diffrent id to

src/sys/dev/pcmcia/pcmciadevs by copying the old entry, changing the DUAL_RS232
name to something else. e.g.

product SOCKET DUAL_RS232_HS       0x00a1 Socket Communications HighSpeed Dual RS232

Then do a 'make -f Makefile.pcmciadevs' in src/sys/dev/pcmcia.

Now you only need to add the new entry to pcmcom.c:

Look for this lines:

const struct pcmcia_product pcmcom_products[] = {
	{ PCMCIA_VENDOR_SOCKET, PCMCIA_PRODUCT_SOCKET_DUAL_RS232,
	  PCMCIA_CIS_INVALID },
}; 

and change it to:

const struct pcmcia_product pcmcom_products[] = {
	{ PCMCIA_VENDOR_SOCKET, PCMCIA_PRODUCT_SOCKET_DUAL_RS232,
	  PCMCIA_CIS_INVALID },
	{ PCMCIA_VENDOR_SOCKET, PCMCIA_PRODUCT_SOCKET_DUAL_RS232_HS,
	  PCMCIA_CIS_INVALID },
}; 

so the new HS entry should now match your card.

Let me know if this works.
