I forgot that I actually have that situation on my dual-boot
Debian/Ubuntu system, and thanks for pointing out that you have an
isseu when you want to use 32-bit and 64-bit kernels. Got it.

I do find though that when I install a new kernel in Debian, GRUB is
not updated, only when I install ad new kernel in Ubuntu.... so I am
always adding the new Debian kernels to the GRUB menu by hand in the
Ubuntu /boot/grub directory. So how do you make a neutral grub
directory with a menu.lst where kernels from all your different
partitions appear?
