Which kernel source 2.6.19 is proper for a Debian distribution?

Hello,

has someone experiance with the installation of the mga-moduls
under a Debian-like kernel of the version 2.6.19.

I haven't found a Debian linux-source-2.6.19, so I tried to install
the marvel-moduls together with a ubuntu-linux-source-2.6.19,
but I failed.

So here my question where can I find compatible linux sources
of kernel 2.6.19.

Regards,

Stefan
