(Debian) Modprobe: module ztdummy not found

I’ve a problem installing ztdummy on my Debian Sarge server.

‘modprobe ztdummy’ gives:

[quote]FATAL: Module ztdummy not found.
FATAL: Error running install command for ztdummy[/quote]

What I did:
Installed Asterisk just fine using aptitude. Then installed kernel sources and build a new kernel. Downloaded the zaptel source using CVS. Edited the Makefile to include ztdummy.

Then did a ‘make all’ and after that a ‘make install’

What did I do wrong?

PS: I have a 2.6 kernel

Help is greatly appreciated.
