Can't say about the latest builds though as I've been running one a week or so old but have just upgraded to the latest so I'll check that later.
Not just 128MB GPU, but yes, OpenELEC will, by default, load SYSTEM into RAM whenever it determines there is sufficient memory available (more than 102MB available, to be precise). On a 512MB Pi with 128MB GPU, there will be 382MB RAM available at boot.
However I don't see a significant performance difference with SYSTEM loaded into RAM, so have opted to have more free memory by adding "noram" to cmdline.txt.
If you are seeing 300MB free with Gotham, I've a sneaking suspicion you're not loading SYSTEM into RAM. A recent Gotham build (128MB GPU) with SYSTEM not loaded into RAM only has ~75MB free.
If you have a file called /dev/SYSTEM then you are booting with SYSTEM loaded into RAM.
