2092d92ef2 New, optional, method to get size of extended memory.
It will be used for getextmem() if EXTENDED_MEMDETECT is defined.
Worked on all tested machines.
Thanks to all testers, especially Martin Husemann!

9fefd40478 In 16-bit mode, mov %ax,%bx is interpreted as mov %eax,%ebx; this
breaks zero-extension of the 16-bit memory size return from the BIOS.
on at least one system, the trash left in the upper half of %eax
causes the kernel to crash during VM system initialization when it
thinks it has on the order of 2**31 bytes of memory to play with.

We now *say* mov %eax,%ebx, but *mean* mov %ax,%bx..

816bb96145 Initial import of new boot code, created by Matthias Drochner with a
little hacking by me. This isn't strictly identical to his 920312
release -- I've hacked it a bit -- but since we are taking over change
control it doesn't matter much.
