I am confused... Before suggesting anything...
(1) All the output in pastebin is when booted into 2.6.26-2, I assume
that the above mount and swapon are also when booted into 2.6.26-2.
(2) When you say that you cannot boot into 2.6.30-1 or 2.6.30-2
because of your swap partition, are you not booting at all into these
kernels or are you booting but swap is not mounting?
(3) When you say that you have migrated from etch to squeeze "without
undue problems", what do you actually mean?
(4i) Please post your grub.cfg.
(4ii) Please post fstab and, while booted into the kernel with the
mount and swapon output above, the following sequence:
swapoff -a
mount -a
swapon -s
swapoff -a
swapon -s
