Just to add: I have tried all grub opptions (normal, non-fb and 
failsafe) on each of them the same thing happens. with non-fb I can see 
the boot process until almost the end, I guess it's the start of the dm 
that triggers the loss of signal in that case.

I tried editing the grub line adding a "3" at end hopeing to get it to 
boot to runlevel 3 but that doesn't seem to work as the behaviour 
doesn't change. Is "3" on the grub line still supposed to work?

I imagine this GMA3600 issue needs solving before the final release as 
CedarTrail Atoms will be in most Netbooks sold this year, and even 
though netbooks are less popular then they used to be, they are still 
selling by the milions especially in Asia.

Let me know what I could do to help debug this.
