I'm not sure that anything was ever broken.

According to the links from my first mail, there has been a bug in UML that caused that problem and I could not find anything that proved that it has been fixed...

You are building the modules against a UML tree, with ARCH=um on the
make line?  I.e. you're not trying to load a host module into UML?

It's not the first time I'm compiling an UML kernel but it is the first time I'm building a 64 bit version. Don't get me wrong, I would never claim to not make mistakes, but the reason is definitily not a forgotten "ARCH=um" or a wrong path, I've triple-checked this...
