Let's see what you have, there.  I don't spend a huge amount of time
looking at lspci output, so the following may include some guesswork.
I think all of those "Unknown device" indicators reflect the kernel
being non-plussed by many of these devices; i.e., they aren't in the
pci.ids lookup table[1], and the devices themselves aren't being very
gabby about what they are, so the kernel's shrugging its shoulders and
saying "Here; this is what the PCI controller said.  You figure it out,
human."

Good.

OK, let's go through your lspci output.  Remember, this enumerates only
hardware devices known to the PCI controller chip.  If there happen to
be, for example, ISA cards, they wouldn't be listed.  Nor is your CPU,
nor your RAM, etc.

Glue circuitry in the middle of the motherboard.  Looking up the PCI ID,
one finds that this (specifically) is "82845G/GL[Brookdale-G]/GE/PE
DRAM Controller/Host-Hub Interface".

This is your Intel 828456 embedded video chipset, it seems.  Looking up
the PCI ID, one finds that (specifically), it's a
"82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device".

A UCHI-type USB-controller chip.  Looking up the PCI ID, one finds that
it's a "82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #1" 
(Three more like that, omitted.)

Controller for your PCI slots.

Controller for your ISA slots.

IDE host adapter chip.  Looking up the PCI ID, this appears to be a
"82801DB/DBL (ICH4/ICH4-L) UltraATA-100 IDE Controller".

System Management Bus.  Can be used (if memory serves) for monitoring
temperature, and things like that.

A PCI-bus sound chip from Intel -- about which it says rather little
other than PCI identity (24c5), IRQ assignment, I/O base addresses, etc.
Looking up the PCI ID on Google, one finds:  "Intel Corp. 82801DB (ICH4)
AC'97 Audio Controller (rev 03)."

Almost certainly some sort of built-in winmodem chipset.  (That's what
Conexant is best known for.)  Looking up the PCI ID, one finds that it's
a Conexant (formerly Rockwell) HSF winmodem.  Hmm!  That makes one
wonder:

You were saying your "Telephony" internal PCI modem isn't a winmodem,
yet I don't see it as a separate item in your lspci listings -- so maybe
the above is it, and it _is_ a winmodem.

And that's your Broadcom BMC4401 ethernet chipset.
