kernel /kernel is the correct setting when you have a separate /boot, the
other only works because of the symlink in /boot. Although when you are
so limited for storage space,, which waste it with an extra filesystem? I
have root at /dev/sda1 on this Eee and no /boot filesystem.

That's because the BIOS makes the boot drive the first disk.

Do you mean the root grub  line or the root= parameter for the kernel?
The first should be (hd0,0) and that is working or you'd never load a
kernel to panic. Have you fiddled with the boot order in the BIOS? That
may be changing the numbering of the drives for the kernel. Have you
tried using sdb2? What is the panic message?
