SLES 11 / openSUSE 11.1 (and later) scripts and tools are at
http://freehg.org/u/bwalle/kdump if you want to take a look at.

The problem is that kdump needs to be integrated into the distribution,
i.e. YaST configuration (vs. RedHat's configuration utilities),
mkinitrd from SUSE (vs. mkdumprd from RedHat [1]), BusyBox vs. GNU
tools.

For example, the reason why SUSE does not use Busybox in initramfs is
that we didn't want to provide additional support for Busybox.
That was a business decision, not because Busybox is not suited or
buggy (i.e. not strictly technical decision).

What I want to say: It's not always *that* easy to share everything
across distributions although I consider that in general as a good idea.

[1] mkdumprd on SUSE is only a script that calls mkinitrd with right
    parameters while the mkdumprd on RedHat builds a initramfs for
    kdump itself with busybox
