Ok I did some additional debugging.
update-initramfs -u -k 3.10.0-3-generic:
3.10.0-3 still boots fine, so update-initramfs doesn't break it.
update-initramfs -u -k 3.10.0-4-generic:
Neither does it fix the problem on -4 kernel
boot arguments:
The defaults are:
linux
Booted system.
Kernel -3:
jean-louis@laptop-jl:~$ sudo modprobe kvm_intel nested=1
jean-louis@laptop-jl:~$
= Works fine, no errors.
Kernel -4:
jean-louis@laptop-jl:~$ sudo modprobe kvm_intel nested=1
ERROR: could not insert 'kvm_intel': Unknown symbol in module, or unknown

Same here with Optimus system:

3.10.0-4 is broken, 3.10.0-3 works fine.

@Jean-Louis Dupond, are you using GDM or are you using a different
display manager? If you're experiencing the same thing and not using
GDM/Ubuntu GNOME, I'll mark the bug as not affecting GDM.

There were absolutely no changes that would cause this in 3.10.0-4
compared to -3 (only 3 patches, one for hyperv, one to enable dynamic
debugging, and one adding a pci id for a realtek sd card reader..). Can
you attach /var/log/kern.log and /var/log/kern.log.1 that will have
historical dmesg info
So its pretty clear i915 not loading is the problem from that, if you
sudo upgrade-initramfs -u -k 3.10.0-3-generic does it break the -3
kernel too? 3.11 allows invalid module parameters instead of preventing
the module from loading so whatever is broken here will be fixed soon
