Yes - take a look at what "dmesg" says. It should give you a hint as to
what's going wrong. This kind of thing is usually because of IO space or
IRQ line, but since you didn't give parport_pc any options it shouldn't be
either of those.

Have a look at Documentation/parport.txt. Briefly, "io=0x...[,0x...]

You shouldn't _have_ to do this though, if things just worked in 2.0.x.

That's fine.
