When you create a directory, ext2 and ext3 allocate one block (4K, usually) for the structures that are needed in that directory. If you put a large number of files into a directory, the kernel filesystem driver allocates another block for that directory. When ls -l stat()s the directory, (number of blocks the directory occupies) * (blocksize) is returned as the size. I've seen directories as large as 64K on an ext3 filesystem, but those directories had about 20,000 files in them.
ReiserFS is different. ReiserFS allocates less than one block at a time for a directory, and its filesystem internals are very different from ext3's. Don't worry about that just yet, though.
Your FAT32 parbreastion was probably mkfs'ed with an 8K blocksize. IIRC, directories in FAT start out as one block long and may grow if they have enough files in them. Or not... it's been a long time since I've looked at FAT internals. HTH,
