VPS license and xen custom kernel problems

[rack::SPEED]

I tried to setup a test environment with XEN 3.2 and cPanel VPS license. Everything work's great, but when i load my custom kernel image my VPS license immediatly stop working:

The exact message was: This machine does not qualify for a virtual/vps license.
The cPanel license server said that your license has been expired.

If i switch back to my dist-kernel every thing work's fine.

Is there an (kernel-) option i had to activate to get my VPS license working?!
