Erk. That should read:
modprobe parport_pc io=0x378 irq=auto
0x778 is the same port as 0x378 (just some extra registers).

Right. The /proc/parport directory indicates that parport.o is loaded.
Subdirectories in /proc/parport mean that the low-level driver (parport_pc
in this case) has detected ports.

That's suspicious, but it might be an artifact of having a fake port on
top of your real one.

I guess this is actually a parport bug. Only one of them should succeed.
I'll take a look.

Yes, that's normal until the ports are actually used by something.

Is that really what it said? The "reports no device" condition should
only ever happen if /proc/parport is empty.
Take a look at your BIOS setting for the parallel port. If it says
ECP+EPP, change it to something else (EPP, for instance).
