A little patch

[Daniel Engstrom]

This is against gfw-0.1 (I have note switched to Stepans version yet)
* exception cleanup
* console in works
* the beginnings of a memory tester

Can anybody figure out why the memtest fails? (boot/init32/memtest.S)

%edx is 0 ?
cause you write

cmpl    $0, %edx        # did we relocate earlier ?
je      .out
        ^^^^ does not reset %eax, which is 0x10000 in the moment

thereby returning 0x10000.

patch:

je      .ok_out

...

.ok_out:        xorl %eax,%eax
                jmp .out

For %edx != 0, I guess the reason would be a memory error ;-)
