I need to retrieve some kernel-source RPM packages (for versions
2.6.32-13, 2.6.32-59-0.7, 3.0.38-0.5 for both i586 and x86_64 archs.

I've tried to use zypper from a registered SLES11 system but I've
been unsuccessful so far to retrieve packages. I've been able only to
install the latest kernel-source package but I need the RPM file for
different versions.

Any help would be greatly appreciated.
