No, I pretty much never install QEMU. I always run it out of a build
directory. Module loading should IMHO work with similar semantics
to the data dir we use for BIOS file loading: one of the places checked
is relative to the executable path.

Maybe we should also have better error messages for "I tried
to load a module and this error is because I couldn't find one",
so the user might be prompted to install the modules package his
distro provides or investigate config if it's self-built, or whatever...

Hrrm. I guess I should investigate that...
