- Use format-independant module allocator.
 - Conditionalise ISA PnP support.
 - Simplify PnP enumerator interface.
 - Improve module/object searching.
 - Add missing depend/install targets in BTX makefiles.
 - Pass the kernel environment and module data in extended bootinfo fields.
 - Add a pointer to the end of the kernel + modules in bootinfo.
 - Fix parsing of old-style kernel arguments.
