Wolfgang, We have got the kernel from MontaVista (linux-2.4.2_hhl20) , I think it might be a modified kernel source. I could run some other card called "Billiontin 56 KBPS FAX/MODEM card" for same kernel and same Target board. I'm getting problem with this specific card(3CXM556 Megahertz Cellular Modem PC Card) only. My card is detected by the kernel and kernel could assign irq 9. The problem is when I send modem string through Minicom it's not responging.
what could be the problem ?

This will not work with unmodified kernel sources; for the modem you need the standard serial driver which cannot coexist with the MPC8xx serial driver (they use the same major numbers). We implemented this some time ago; see the linux-2.4 module on our CVS server and search "drivers/char/serial.c" for "MPC8xx_UART".
