If you have enough disk space to accomodate your data *without*
compression you could do the following:

- boot a 'rescue system' (I recommend knoppix) from CD or usb
- mount both your partition and the one with the free space
- rsync -avx your data to the free space
- reformat your partition to ext3 (all data will be lost, so make sure
you have good backups!)
- rsync all your data back to the new ext3-partition
- adjust your /etc/fstab (replace reiserfs by ext3)
- cross your fingers and reboot

tar would work on similar lines. tar can use compression, rsync is
probably faster (plus you have all your files as a backup; if one of
those files would get corrupted not everything is lost).

Take care that you properly understand each step, verify the options. Be
aware that a typo may lead to data loss...

Take care, good luck!

If it's VFAT, it'll retain case, though you can't have two files with the
same name seperated only by different cases in VFAT.

That would only be the filename of the tar-file, so it doesn't really
mater.

That's not true. See the mount options for vfat (shortname=...).
