I'm not an parport expert at all, I had just a look at the man page,
so I may be wrong.

The manpage says: "Note that if you are using a Kernel 2.2.x or
better, the first parallel port is named lp0 regardless of the base
address.". So 0x378 is probably right.

Maybe with an older Kernel?

The man page also states: 

"This backend does support parport sharing only if you have a kernel
with ppdev support." 

Did you try without your printer? You don't seem to use the ppdev
module. Did you try using /dev/parport0 instead of the port numbers?
