Actually, following Murphy's law, I found the cause minutes after the last post...
But, at least I found how to reproduce it :)
I use KDE. If I disable compositing (shift+alt+F12), then the second monitor works without being mirrored.
With compositing enabled, X crashes, and happens as first reported.
On my previous post, the battery was low, so KDE disabled the effects. As a result, I thought it could be related to resolution.
But actually, it's related to the desktop effects being enabled or disabled.

Now, the real question: is this a limitation of the intel hardware /
driver of not being able to handle dual head with compositing or is this
a bug? Could someone using gnome test whether dual head works with
compiz (desktop effects) enabled?
