afaik Finder creates a ._ prefixed file for metadata that it can't store natively. I'm using netatalk 2.2, so the behaviour might be different back in 2.0.5, but I thought netatalk managed that and put the metadata in a .AppleDouble/ directory.

In any case, look at the "usedots" and "invisibledots" options for the share to avoid the ":2e" business.

My typical options in netatalk 2.2 are:

options:usedots,invisibledots,upriv,tm

Good luck,
Matt.
