Obviously so. /proc/sys/kernel is a virtual file system, and gets reset every time you reboot.

The fix is either to compile the required values into the kernel to start with (rather a long-winded approach) or to edit a script to make the 'echo' command execute at each reboot. On Red Hat and Mandrake, that's done by editing /etc/sysctl.conf. But it may well be a different name on SuSe.
