Attaching dmesg output from a virtual machine which doesn't seem to have
a (virtual) parallel port. This part:

[   63.962283] parport_pc 00:05: reported by Plug and Play ACPI
[   63.962469] parport0: PC-style at 0x378, irq 7 [PCSPP,TRISTATE]
[   64.061723] ppdev: user-space parallel port driver

was after I manually killed "/sbin/modprobe -q -- parport_lowlevel" which
was started during boot.

Tomorrow (when I'm in the office) I'll check what happens when I add
a parallel port to the VM and also send you dmesg output from the
physical machine where I first noticed the issue. I'm quite sure it has
parallel port on its motherboard but it might be disabled in BIOS, I'll
have to check.
