can you guys ask someone internally about it also, there is a driver somewhere in Google also for driving the LVDS->HDMI adapter but I'm not sure what i2c bus its hanging off.

may or may not be the thing.

I'll see if it works...
Is there a public clone URI for that repo? I dont want to have to download the full ChromiumOS...
Okay, I guessed it right: http://git.chromium.org/git/chrontel.git
Simply running the resulting executables didn't work, it fails to detect the chip, the code also references accesses through GPIO and seems it wants an nm10_gpio driver which isn't in my kernel tree. My board is an NM10 chipset system, as is the target "Cr48 Chrome Notebook" so it could well be the same hardware.
I cherry-picked the nm10_gpio driver from the ChromeOS kernel, but while it worked fine the chrontel driver still couldn't detect the chip:
XAUTHORITY=//home/mythtv/.Xauthority ./ch7036_monitor -v -p ./ch7036_monitor: starts Found device ID 0xff ./ch7036_monitor: Fatal: Device ID 0xff not the expected 0x56
So either it isn't a ch7036 or I'm still not doing everything necessary to expose it.
