No version has ever automounted partitions for me (I've used 6.06, 6.10, 7.04, 7.10, and now 8.04). 6.06 and maybe 6.10 did NOT support NTFS at all (only read, no write) but 6.10 did allow you to install an experimental NTFS library, full of caution warnings, that could write. It actually did work pretty well, but none automounted drives.
If you want to add a drive, you have to edit /etc/fstab (File System Table, the file that contains all the drives that the computer mounts when it boots up). Look online to find info on how to add different types of partitions to it. You have to put the device name (/dev/hda1, /dev/cdrom, etc), the mount position (/media/disk, /media/windows, etc), and the partition type (ext2fs, vfat, ntfs, etc).
