[PATCH] linux-initrd: Add AHCI modules.

One problem that Mark Weaver and I encountered when intalling the GNU
system on our Thinkpad X60s was that initrd couldn't boot from our SATA
hard disks without passing additional kernel modules in the
operating-system declaration.  I think it would make a lot of sense to
have these modules loaded by default, given the widespread use of SATA
disks.

I doubt that hardcoding the AHCI module names into linux-modules is the
preferred way to do this, but I wanted to propose something simple to
get the discussion started. :)

Thoughts?
