[haiku-development] Intel GMA X4500 Video Handholding?

I previously inquired about supporting my LCD display's 1400 by 900
resolution, and it was suggested that I add the PCI Device ID for my
graphics controller to the intel_extreme driver.
The Detailed tab in the Devices app says that the Device ID 0x2e22 is
a VGA compatible controller, but my motherboard doesn't have a VGA
socket on it. The 0x2e23 is just listed as "Display controller",
without any mention of VGA. Would that be the controller for my DVI
port?
I think the 0x2e23 is an Intel Graphics Media Accellerator X4500 or
maybe X4500HD. I'm having some trouble finding the Intel datasheet
that lists the 0x2e23 Device ID.
I tried just adding 0x2e23 as INTEL_TYPE_GMAX4500 to:
haiku/headers/private/graphics/intel_extreme
and then added INTEL_TYPE_GMAX4500 to the supported_devices table in:
haiku/src/add-ons/kernel/drivers/graphics/intel_extreme/driver.cpp
I did a rebuild from the top-level, then verified with ls -l that the
intel_extreme driver had been rebuilt. I installed it on my target
box, rebooted and...
... still got VGA video - my video controller is still not recognized. ;-(
Still I've made some progress in being able to figure out where all
the sources are, and to do builds and stuff.
Can anyone make any suggestions as to how I can figure out why my
controller is still not recognized?
I'm about to hook up the serial port to my Linux box so I can look at
debug output. However my test box' serial port is on a PCI card -
will that work as-is, or will I need to patch the sources somehow to
be able to use a PCI serial port?
There is an integrated serial port on the motherboard, but I don't
have the necessary cable.
This is all very exciting, to finally be hacking Haiku drivers.
Thanks!
Mike
