With ppdev.ko loaded, libieee1284 lists the wrong number of parallel ports. You
can check this with 

    /usr/bin/libieee1284_test 

Having one parallel port in the system (a PCI card), I get

    Found 3 ports:
       0x278: 
       0x378: 
       0x3bc: 

The addresses are even wrong because that are the usual PC addresses that are
not valid for PCI addon cards.

The problem is that the "number of links" property has changed in the kernel
for 
the /proc/sys/dev/parport property.

The attached patch fixes this.
