The point was to speed up boot by streamlining the swap selection process (and avoid activating eMMC swap then swapping-off a few seconds later).

It should be safe to throw in "if /lib/modules/current/ramzswap.ko insmod /lib/modules/current/ramzswap.ko disksize_kb=65536 swapon -p 5 /dev/ramzswap0" before MMC-device swap detection happens.

However, I would strongly suggest testing out ramzswap options before putting it in. The results people are getting are wildly variable. If the pre-Fremantle guys say it's good, we need to get our kernel tunables just right (avoid everything getting put into ramzswap, and hitting swap+cpu hell, etc)
