Possible fix for 32-bit guests

Attached is a patch that fixes problems with 32-bit guests on 64-bit hosts. For example, I got damn small linux 0.4.10 to boot with this; previously it segfaulted during init.

If you have issues with 32-bit guests, please test with this patch and report. Even if you don't have any issues, testing your usual guests is appreciated.
