are u using printk() for tracing the function calls. then it might
happen that xterm is just not displaying the output. i'm not familiar
with pcmcia, so please forgive me for any foolish comments.

BTW, i didn't understand what u meant by operating from console. what

normally X server should in no way affect the functioning of a device
