Hi Heiko, Udo,

could you please check if it's a good VM identification?

> dmesg | grep 'DMI:' | grep -i qemu > /dev/null

# dmesg | grep DMI
DMI: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.8.2-0-g33fbe13
by qemu-project.org 04/01/2014

i didn't find anything useful yet in busybox' applets. dmidecode is not
very big (~100kb) but i'd rather use kernel buffer.
