PCMCIA GPRS cards not works,help...

[Magikor]

Hi,
I have a PCMCIA GPRS card,but when I insert it to my machine(Based on PXA255,linux-2.4.18-rmk7-pxa3)it appears two serial ports,so strange,can anyone give me a hand?
In order to avoid the "Bad Vcc" error,I have delete the two lines in cs.c
/*
    if (s->socket.Vcc != req->Vcc)
	return CS_BAD_VCC;
*/
Following is the detail debug info:

----s->socket.Vcc=33,	req->Vcc=50------
------<6>ttyS03 at port 0xf60003f8 (irq = 46) is a 16C950/954
ttyS04 at port 0xf6000400 (irq = 46) is a 16C950/954
Division by zero in kernel.
