Almost too easy...

So I tried with kms right from the boot, and it didn't change anything.
Same complete crash with black screen after some random time.

Don't know if it helps, but to know if the crashes also happen without
X, I'll leave the laptop boot to console with kms and stay there. This
will have to wait for tonight (after work) so I can leave it on console
long enough.

Thanks,
