Today I tested the Lilliput (attached as a secondary display for my notebook). It works very well. It has a very nice appearance, looks like a good quality product (I thought it was going to have a cheap look but I was totally wrong. It starts with the nice box, all accessories and the screen itself is very nice).
I didn’t test it on the CarPC yet because its Sunday and my CarPC "test environment"

is at my work (using a part of the desk on my cubicle). I have a baby and it wouldn't be safe, his curiosity won’t leave my CarPC alone on the home table.
I will take the lilli and m2-atx to the office tomorrow and will try it on the CarPC when I have time.

I have programmed the
auto power on feature, following the instructions of this
thread.
The only thing I am worried is about setting the proper resolution
800x480. My IBM T60p notebook doesn’t have this resolution available, I've tried Ultramon and Powerstrip but no luck. I think its a limitation of the ATI Mobility FireGL V5200 card. But that is not a problem, since I will not use this as the CarPC. I was just anxious to test the touchscreen and see if the resolution is good (it is).

I hope that the onboard VGA adapter that I have in the CarPC supports that resolution. I will test tomorrow or the other day.
You can set any resolution and the lilliput will "stretch" it to fit full screen. But to get the best image it is necessary to use native resolution,
800x480.
I also bought that book, the
Car PC Hacks, it is very interesting! I recommend it! It seems to have good tricks, and it explains every aspect of the CarPC.
