[PATCH 0/3] Boot speed patches

Ok, here is a set of three patches which testing seems to say give us
a fair chunk of time back from the boot 'kernel initialisation' time.
There are three patches.  The first is a patch to make isapnp_init async,
the general feeling was that this should be safe but has not been tested
in the face of any actual ISA hardware.  The second is a patch which helps
i915 boot performance caching the EDID information for the LVDS panel
which is by definition static.  The third is the async_populate_rootfs
patch from Surbhi.

I am proposing to push these to Lucid as soon as the Alpha-1 freeze
is lifted.
