Now that surprises me. The chosen cpu setting for the kernel triggers
an error in _compiling_ qemu?
Or is this a special bug with the Fedora i586 kernel?

Well, my laptop system, where this also is reproducable, is totally
compiled with -march=pentium-m and the kernel is configured for a
Pentium-M.

Do you have more information on how the kernel triggering this is
possible? And why it is happening with wemu-0.9.0 but not with 0.8.6?
