Strange Dmesg error

[Dragoncrest]

	Today after recompiling my kernel I noticed something on my screen that 
caught my curiousity.  I got the following message:

Apr 23 22:22:05 bsdbox /kernel: ppi0: <Parallel I/O> on ppbus0
Apr 23 22:22:05 bsdbox /kernel: unknown: <PNP0000> can't assign resources
Apr 23 22:22:05 bsdbox /kernel: unknown: <PNP0303> can't assign resources
Apr 23 22:22:05 bsdbox /kernel: unknown: <PNP0c02> can't assign resources
Apr 23 22:22:05 bsdbox /kernel: unknown: <PNP0501> can't assign resources
Apr 23 22:22:05 bsdbox /kernel: unknown: <PNP0700> can't assign resources
Apr 23 22:22:05 bsdbox /kernel: unknown: <PNP0401> can't assign resources
Apr 23 22:22:05 bsdbox /kernel: unknown: <PNP0501> can't assign resources

	Anyone know what this means?  All I did was add the following lines to my 
kernel config.

options         VESA
device          pcm
options         PNPBIOS
options         USER_LDT

	Would any of those have generated the said errors, and are they something 
to be concerned about, or can I safely ignore them?
