I have the following: (slightly modified from LINT)

controller ppc0 at isa? port? tty irq 7
controller ppbus0 at ppc0
device     nlpt0 at ppbus?

There's a description of this message in the source. Check it out in file:
/usr/src/sys/i386/isa/intr_machdep.c. Look for isa_strayintr.

Cheers,

  Bart.

BTW. It came as a shock when I discovered the following in dmesg after
rebooting the first time having upgraded to 3.1-stable...

Probing for PnP devices on ppbus0:
ppbus0: <HEWLETT-PACKARD DESKJET 850C> PCL,MLC,PML
nlpt0: <generic printer> on ppbus 0

like, wow!
