This is strange as the sound driver isn't expected to initialize at all
on this model since it doesn't recognize it. Or maybe alsa was trying to
load a bogus module ?

Also, be careful with parport, remove it from your /lib/modules. Things
like CPUS tend to cause it to load and it will render your kernel
unstable.
