I've tried 2.6.16-rc6 now, and get the following message at the end
of the kernel boot process:
EXT3-fs: mounted filesystem with ordered date mode.
VFS: Mounted root (ext3 filesystem) readonly.
Freeing unused kernel memory: 308k freed
Warning: unable to open an initial console.
Kernel panic - not syncing: No init found. Try passing init= option to
<0>Rebooting in 120 seconds..
That was the clue I needed: I then looked at the partition numbering and
found that the new kernel enumerates numbers partitions differently (my
root partition was /dev/sda5 with 2.4) and assigns numbers that
correspond to those listed by fdisk -l.
But when I try to boot with root=/dev/sda7, activating swap and mounting
of the boot partition doesn't work and also keyboard input is ignored
when I'm dropped to the maintenance prompt.
I'll provide my parition table as printed by fdisk here to make my
comments above clearer:
# fdisk -l /dev/sda
Disk /dev/sda (SGI disk label): 64 heads, 32 sectors, 8748 cylinders

It seems from the boot prompt of the 2.6 kernel, that the following
numbers are then used:
sda1 sda2 sda5 sda6 sda7 sda9 sda11
I'm not sure, but this seems to be a good idea, if it wasn't for the
lack of backwards compatibility. So perhaps it would be smart to have
some boot option to switch from one numbering scheme to the other, to
allow for a smooth transition?
Please comment. But with non-working PS/2 keyboard and non-working
/etc/fstab for both kernel version, the 2.6.16 image is pretty worthless
to me at this moment.
I assume that my problems with 2.6.12 where for the same reason, but
that I didn't even notice the root filesystem (which indeed is the boot
partition) was mounted and the kernel rebooted immediately when no init
