probably you missed `make clean mrproper` before building UML.
Time to try it myself :)
# sudo apt-get install linux-source-2.6.18=2.6.18-8
...blabla...
The following packages will be upgraded:
linux-source-2.6.18

DOH! oh, now I remember :) we have a fix in the user-mode-linux package
see here:

you may also want to try build the user-mode-linux from source by
yourself, eg:
apt-get source user-mode-linux
cd user-mode-*;
dpkg-buildpackage -uc -us -b -rfakeroot
