That means that the port in question doesn't allow us to read the data
register _or_ the control register. Rats.
Is there anything in the BIOS about the parallel port? Also, does it make
a difference whether or not anything is plugged into the parallel port
(I'm guessing not)?
David Campbell has a tool called id_probe, for detecting parallel ports.
Could I get you to give that a go? I'll send it to you in private mail.

With the tmw patches, you can get parport_pc to surrender just by
specifying the base address, so io=0x378 irq=5 should take care of that.
As far as ppa is concerned, I don't really know why it doesn't work. Once
ppa finds out the port's base address, it pretty much does its own thing.
