Well, I am not completly sure what we are talking about here ... ;-) The
usuall way if someone wants features to become part of the kernel is via
the community, in this case via the network guys as Olaf suggested or if
it is a plattform specific thing via the plattform maintainer, which is
David Engebretsen <[email-masked]> for example for PPC at IBM.

In case that there is for some reason no solution going this path, IBM
has the possibility to request features from SuSE via the brands and via
the LTC. This is organized by Mark VanderWiele <[email-masked]>.

To be more specific: For 2.4 kernel the door is allready closed since
some weeks. In case you would like to see this patch in an upcoming SLES
9 and a 2.6 kernel, get in contact with Dave and Mark.

Hope this helps for the moment.
