kernel modules not loading at boot after upgrade

[Ernesto Domato <edomat@gmail.com>]

Hi, I'm using Debian AMD64 Sid/Experimental on a laptop and after
upgrading it yesterday my touchpad, sound and battery applet stop
working. I found that the kernel is not autoloading the respective
modules (psmouse, snd-hda-intel and battery) on boot and even placing
them on /etc/modules doesn't solve the problem.

The only solution is to load the modules by hand (using modprobe)
after the system finish loading but I'd like it to behave as before
:-)

Thanks in advance.
