Okay, we'll compare apples to apples: how's the 32-bit-mode code generator
for the 386 coming? If you don't have that, you just have a little faster
80286. Rewriting the code generator and recompiling everything strikes me
as rather more work than hacking up the MMU section of the kernel.
*Especially* since the 286->386 conversion is also going to mean hacking
up the MMU stuff to cope with 32-bit addresses.
