Can you reboot off the old kernel? Debian doesn't usually remove old kernels. It leaves a big long chain of them accessible in lilo.conf or menu.lst. I don't know anything about software raid, but if you can fdisk -l /dev/sda and see /dev/sda1, you shoudl be able to mount that filesystem. But since you said it's raid 5, I am guessing you need to mount at least 3 filesystems simultaneously to get your system mounted. I wish I knew the right questions about mdadm to ask. I'm forwarding your email to someone else who uses software raid.
