I might be wrong here, but it looks like your calculation missed out buffers and cached usage. Your 120MB accounted + 388.70 (cached + buffers) = 508MB approx. But you did paste some output regarding ext3 inode and buffer slabs.. I'm not sure if SLAB is used for storing buffers and cache data - maybe it's just metadata that is stored in SLAB? (i'm stabbing in the dark - my kernel book is not with me) Hopefully someone else will be able to give you a conclusive answer.
