I have tried ubuntu mainline builds of:

2.6.32.21
2.6.32.22
2.6.34-rc3
2.6.35-rc1
2.6.34-drm-intel-next

None have worked yet...

Apologies...mistyped. I meant the LVDS internal display, not connector.

When I boot without the external display, I am never able to ssh in -
and I do not get the sound that typically plays when X is booted.

I've put this onto a serial line, and it seems to hang sometime in
init...with some indicators that it is when it switches over to the
higher resolution console...but the screen is black, so this is really
just a gut feel.
