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.
