[Debian-eeepc-devel] [PATCH] Load eeepc_laptop and set SHEngine in background

[Luca Niccoli]

The attached patch sets adds a line to /etc/modprobe.d/eeepc.conf to make
modprobe fork to background while loading eeepc_laptop, and modifies the
init script accordingly to wait for it to be loaded.
It also makes the init script do the SHEngine setting in background, as that
is very slow.
