Hi Fabrice, As most kernel developers consider non-GPL modules to be illegal, I would oppose altering a single line of kernel code to support such a module, as that would seem to be complicit. If QVM86 (or a compliant kqemu) ever gets into mainline, we can certainly do the mods then... Sorry if this disappoints, Rusty. -- Help!
