Can you do an install with the thing turned off, and then
- compile the kernel with CONFIG_PCI_DEBUG
- boot with the parallel port enabled, and send as much of the bootup
output (and /proc/iomem and /proc/ioport) as possible
- boot with the parallel port disabled, and send the same output for that
working case.
I have no clue why the parallel port should matter, but it could change
some resource allocation issues.
