Aldert, what exactly do you mean when you say, "The debian kernel
seems to be 2.2"?
Are you actually running a Linux 2.2.x kernel on a Debian box? That's
verging on crazy, as 2.2.x is ancient. Debian 3.0 Stable,
now very old, shipped with kernel 2.4.18. I believe it also included
a 2.2.x kernel, but I'm not aware of any reason to ever use that.
The current Debian Unstable and Testing have both 2.4.x and 2.6.x
kernels.
