Not sure how you reach that conclusion. Your current /dev/hdc1 starts
at cylinder 65520, so it actually the 7th partition on the disk.

If you swap hdc1 and hdc2, then the logical partition names will indeed
stay the same, but your partition table is still out of sequence, and
I know I have come across software that does not allow the extended
partition to be anything other than the last allocated primary partition.

I believe that both lilo and grub are capable of booting from any primary
or logical partition. But you main need you may need to be able to boot
from a rescue disk to re-install your boot blocks.

I would make sure that you have a bootable rescue floppy or CD just
in case you need to re-install lilo after the partition name changes
have taken effect. It is quite a while since I last used lilo, so I
don't recall how much is needed.
