Why is that? On an embedded system with only a few megs of RAM it would be a 
completly waste on resources if I had IDE, serial, orinoco and whatever driver 
loaded all the time although I have only one CF socket, thus can only use one at 
a time!

How?
Is there a better way then
	basename `readlink /sys/bus/pcmcia/devices/0.0/driver/module`
?
