  Hmm, this may be a problem, since only the 3.0 branch of Zorp is
compatible with Linux 2.6... (To be more accurate, only TProxy 2.0 has a
Linux 2.6 version available, and only Zorp 3 has support for TProxy

  Yes, as I've stated above it's incompatible with TProxy 2.0. Please
try to upgrade to Zorp 3 GPL, it is probably a better choice than
downgrading your UML kernel to 2.4. If you have any compilation
problems, please let us know.
