I think so

I usually refer to http://user-mode-linux.sourceforge.net/old/index.html . It
probably is not really the latest version, but it has been good enough for me
so far.

1) gcc 4.1.2 looks very old. Even my debian stable here already has 4.4.5.
2) I use the command "ARCH=um make linux". It will probably not make any
   difference, but ...
3) Sometimes UML is a real pain. When I upgrade my testing kernel, I usually
   have to spend some time searching the internet for fixes. I do not remember
   this error, tough. You can find my current (3.0) kernel at
   http://repo.or.cz/w/cor.git , if you are interested.
