I'm not an expert -- and this is perhaps not a direct answer -- but I 
believe those messages come from hardware that is not handled via ACPI 
(obviously); but they can still recognized and attached to something else.

For instance, on this (old) motherboard I have I get similar warnings 
related to serial and parallel ports, but they're picked up later as 
connected to an "isa" bus.  So presumably they can and should be 
recognized, but it's no big deal that they're not.

Probably the parallel (printer) port itself, since "ECP" is a related 
standard.  It might show up as an "lpt" later.

I'd file this under "obscure chipset stuff", but someone else might know.

(It looks like the sort of thing that is either not important (fan), and 
doesn't matter much; or really important (root pci bus), and if it didn't 
work it would be obvious.)

I'll be the first to admit my lack of knowledge about graphics cards, but 
with AGP I think it's not that uncommon to see cards that "borrow" memory 
from the motherboard rather than carrying memory on the card itself, 
especially on the low end.

An internal modem?  Google says "SoftV92 Data Fax Modem with SmartCP", 
which sounds about right for "miscellaneous".
