This is just a trick so i can use bpb_size in the kernel later,
omitting things that are not relevant to interfacing the FS.

Revert to more sensible kernel.bs boot scheme
I think i should consider it a necessity that the kernel is accessible
as a regular file. This makes installing rdos on another blockdev
much easier.
