Looking at my desktop PC's dmesg, it seems to probe the com-devices next,
and the machine indeed lacks any external com ports. I still have to find
a blank CDR to test a kernel w/o com, but I still wonder if the "com"
probe routine should really hang the machine in such a case.

With all these USB devices popping up, it can be expected that more
vendors stop shipping machines with com (and PS/2!) in the future. :/
