There is an error in the bios code (I haven´t found it) with the address
which gets insert into the acpi tables (rsdt address) and the address
which is inserted into the smap tables when the memory of the emulated
machine is under 19MiB RAM!
From 19MiB RAM on the address in the smap tables and the address of the
rsdt in the acpi tables is correct. Maybe someone with more experience
with the bios code can look on this?

It's a Bochs Bios bug. See my mail <20070910132245.GA2926@chrom.inf.tu-dresden.de>
from Sep 10 on the Bochs developer mailinglist for a patch.
