Hehe, check out http://www.abwillms.demon.co.uk/prog/kernel2.zip (readme
available from http://www.abwillms.demon.co.uk/prog/index.htm, look for
`Bill Currie's PC Bootable Kernel'), it does all the above, with a few
extras.  It's meant for getting started, so it's really incomplete, but
it does boot successfully.
