1394 w/Core 2 Duo - 945PM Express chipset (Dell Laptop)

Hi Everyone...
I'm supporting a proprietary software program and 1394 audio device,
but that is irrelevant to my question:

I am testing a brand new Dell Latitude D820 laptop which uses the 945PM
Express Chipset and the Core 2 Duo (T7200) 2GHz CPU. It has an
integrated 1394 controller and I'm not sure if it is part of the
motherboard chipset, CPU or some 3-rd party controller... When I click
on the "OHCI Compliant IEEE 1394 Host Controller" in Device Mangler,
the hardware ID shows:
PCI/VEN_1217&DEV00F7&SUBSYS_01CC1028&REV_02
As far as I can tell, VID 1217 belongs to O2Micro.

The Problem:
This piece of audio hardware can't successfully talk to the software
over the built-in 1394 port on the Dell laptop. I have tried the
MicroInnovations 1394 Cardbus adapter, and it works fine with it on the
same laptop. I am not a software programmer, so I can't provide any
details there, but we do know that it "appears" to be a communication
thing, where it might be dropping data.

We have also observed similar communication issues on a Mac Book Pro
(running XP) which is also based on the Core 2 Duo system, so we
thought this might be related to whatever the Core 2 Duo systems are
doing.

Has anyone had ANY issues so far related to the Core 2 Duo's or the 945
Express chipsets?
I am already working on having the software/firmware people look at
this, but so far, I am the first one to suspect this Core 2 Duo system
for this problem.

Again, the software/hardware works the same machines with an add-on
1394 controller.

I don't expect any solutions to this just yet, but if anybody who reads
this could tell me if they have heard about or seen any strange
FireWire issues with these types of systems, that would be appreciated!

Thanks,
Jonas
