This is your problem.  Most likely, the vfat module in 2.0.30 is far too
old to understand the filesystem on the partition.  You realize that
there have been 3 major releases of the linux kernel since 2.0.30 has
been released?  It's now 2.6.x.

The error reported originally was:

> VFS: Can't find a valid MSDOS filesystem on dev 03:41.

Unfortunately, they neglected to note that the numbers are in hex.
0x41 == 65.  There's nothing wrong with your partitions.

Yes it is a dinosaur.
