The problem is that, fx after installation, you have entries that can
boot the system. 

If #kopt is changed and a homecompiled kernel is installed
(kernel-package) and removed (dpkg --purge) then the original entries
are changed according to the new #kopt setting.

Then the system may become impossible to boot.

If you 1) install the official way, 2) install raid (as this is not
possible with my system because of other bugs) 3) compile a kernel the
official way and de-install the new kernel, the system cannot boot.

This must be a bug. Settings should reflect changes to menu.lst - NOT
old entries. Apparently grub mess up the entries in menu.lst.
