You may want to have a look at http://www.lpsg.demon.co.uk/pnp-linux.html there's a patch for 2.0.33 and 2.1.88 kernels to support PnP. At least the page has links to HTML and ASCII versions of the documentation mentioned. Last i checked i couldn't get it to regocnise my pnp-serial or pnp-parallel ports, but i didn't try too hard either (it found my olp3-sa3 onboard sound)

The PnP-patch also has userland support for fun features of pnp.
BTW, is this going to be in the mainstream kernel anytime soon? I already see bits of it in Configure.help, but none of the actual .c files in drivers/pnp.
