Will,
What are your parallel port settings in BIOS?
Do you have Plug-n-Play OS enabled in BIOS?

The current Via-specific parport_pc.c code forces on the best possible
parallel port modes the chip can handle.  In retrospect, what it should
be doing is reading the configuration BIOS has set up, and not touching
it.

I am not sure that I agree, however, that an "irq=none" on the kernel
cmd line should affect the operation of the Via code.  I would much
rather fix the Via code as I suggest above.

Time to look for and drag out the old Via laptop...  Oh well, I needed
to debug the Via audio code some more anyway. :)
