ok, so Olimex sells quite a few kits with the SD/MMC socket, but i am unable to find any software to support it.

Does anyone know of some good source for supporting FAT16 or FAT32 ?

http://efsl.be/ is one option for FAT support. You still need code to talk to the SD card.

Here is a reference for a simple FAT16 only filesystem that only supports 8.3 filenames, but it is relatively simple.

Check out this MP3/AAC player based on the Olimex SAM7-P256 board:

It uses the CHaN FAT16 filesystem (http://elm-chan.org/fsw/ff/00index_e.html) -- a fairly simple implementation.

A SD card library is provided, properly abstracted as "disk I/O" access for the FATFS code.

Just as an FYI i also found this company who makes a really good FAT implementation.

Code for Atmel and NXP ARMs is included with EFSL. And even still - writing the SD access routines is not particularly difficult.
