I own a laptop which runs Linux and PD runs very smoothly on it.

The model is an Acer Laptop 528 TXV (PIII, 850 MHz) and it worked
right out of the box (with LAN builtin, PCMCIA, DVD, USB, sound
bidirectional). Also APM seems to work (without the suspend to disk
hibernation mode). Acer kinda support Linux (at least they claim to be
supportive) although there is no Laptop with preinstalled linux

If you want to learn more about Linux on Laptops, follow the top link
if you search for "Linux Laptops" at google. It'll lead you to the
Linux Laptop site, which is a Database with howtos for installation on
hundreds of laptops provided by their users and sorted by brand. 

I have the impression that right now it seems to be hard to find a
laptop, which doesn't run linux although there might be minor problems
with exotic parts sometimes. Generally speaking: If linux is supported
and the soundcard works with ALSA you're fine concerning pd.



The whole PnP issue is a little unclear to me since the interrupt
configuration of pnp cards under linux is done in the /etc/isapnp.conf
file (with very clear explanations how to do that in the isapnp
howtos), but I'm no hardware specialist.
