Bug#421779: Poweroff doesn't work on Sony VAIO S4M

[muzzle <muzzle@gmail.com>]

Hello,
I can confirm this bug, I'm experiencing exactly the same issue on my
Sony Vaio S5M (a slightly updated S4M).

I'm stuck with a 2.17 kernel because every later kernel my laptop
refuses to power off after the shut down (I used both official debian
-686 kernel and the vanilla ones).

If you need to I can provide whatever log file for the
linux-image-2.6.18-686  package (or for 2.6.21).

Bye,

Emme
