Yes, but is that a 256MB "b" or a 512MB "b"? I'm guessing the former, I just wanted to be sure.

No - it probably is, although it could also be due to the new build which seems to make about 7MB more RAM available to ARM compared with #0703. Repeat your test with zram disabled and see if you get the same performance benefit.
Edit: Forget the comment about #0706 making an extra 7MB available - I've just checked again and it's maybe only 1MB extra free on #0706. I thought I noticed a 7MB difference while creating interim builds but it may have been due to some SQL breakage in xbmc that resulted in less memory being used (eg. no movie or tv library being loaded!)
Though really I'm just pointing out that using RAM for swap is (to me at least) a little counter intuitive, but it is possible that zram swap has a benefit over traditional swap because of the compression.

On a 512MB RPI, swap (zram or not) should be much less of an issue and rarely needed, if at all.
