There is also the plan to do parallel device probing inside the kernel

Right, this means that the way of passing "root=/dev/hdc2" will no
longer work because /dev/hdc will sometimes become /dev/hde. If you are
serious about going to implement this, first add (to linux-2.6.16?) a
boot-time warning if the kernel is booting without initramfs. The
warning should say something like this:
WARNING: you have booted the kernel without initramfs and passed an
explicit root device name. This will no longer work when the kernel will
probe devices in parallel (i.e., since linux-2.6.??) because device
ordering will be random. Please create an initramfs that mounts the root
device using some stable attribute, like label or UUID.
