After toying with the udev rules, I've managed to pinpoint it to a 
single rule set; I failed to find out which rule causes it though, I 
believe it may be caused by a combination of rules.

Please note that I am _not_ running a system that has PCMCIA; I want the 
rules for udev to be generic, as I will run the same system on a 
notebook as well. The file is composed of rules from pcmciautils 
software package (for handling PCMCIA with latest kernels).

Thanks in advance for any help, it'd be nice to resolve this one:)
