is grub executable on i386 only, or does it requre 32bit support in
the kernel? I turned the 32bit support in the kernel off because I
didn't use it, tried out some powermanagement options and now made
another kernel with different options, but I can't set it up:

Well, update-grub updates menu.lst but does not call grub if device.map
already exists, AFAIK.

Shouldn't there be an amd64 version of grub?

Hm, I thought I had to run grub to get a new kernel installed. So
changing the menu.list is all it takes?

There should be, but there isn't. Poking around in the source I found a
pointer to a binutils bug, http://bugs.debian.org/244498. Apparently
nobody is really interested in resolving that issue, so you're on your
own if you would like to fix it.
Given that grub is in maintenance mode, you probably have to switch to
grub2 aka grub-pc for a 64-bit version if you cannot fix grub yourself.

Yes, grub is not lilo, you know.

Well, as long as it works, it doesn't really matter.

Yeah --- when they switched to grub, I had to figure out anew how to
get kernels installed, and that seemed to involve running grub. Since
then, I just did it that way and it worked.
