Karmic upgrade failed, possible currupted partition/filesystem

After upgrading of a working Jaunty to Karmic final, it would not boot
into the system and instead hang in the initramdisk. I did NOT yet
upgrade to ext4 or grub2.

Booting with safe mode reveals that it could not find my main partition
(which contains my now Karmic installation).

Booting into a second karmic system on the sda2 reveals that sda1 is
indeed not visible any more:

$ ls -la /dev/disk/by-uuid
total 0
drwxr-xr-x 2 root root 80 Oct 30 09:22 .
drwxr-xr-x 6 root root 120 Oct 30 09:22 ..
lrwxrwxrwx 1 root root 10 Oct 30 09:22
500a11a1-86bd-4609-96ca-78797dfb772b -> ../../sda5
lrwxrwxrwx 1 root root 10 Oct 30 09:22
b17e1aff-9f02-4fbd-81e5-9b1e6899baad -> ../../sda2

Nevertheless, I can mount my main partition when I directly
mount /dev/sda1 from the second installation, so the filesystem is
intact.

When I start "Palimpsest", it shows my first partition as "54 GB
unrecognized", which is a bit startling.
