OK ==> the device cannot be accessed. Either the I/O address "0x378" and 
partport type "epp" is incorrect (you did not answer my question on 
that) or the parallel port is not operational (power off, etc.).
Please check what is actually selected in the BIOS of your system.

Try "modporbe parport". If the module does not exists, configure and 
rebuild your kernel with parport support.

In the meantime I'm going to apply the fix Jan mentioned.
