Ideally, we think it would be best if the existing MTD-based ps3vram driver
would be replaced by the new block-based ps3vram driver before 2.6.29 is
released. This would relieve the burden of supporting two different swap space
schemes on PS3 (swap on /dev/mtdblock0 vs. /dev/ps3vram) from the distro
maintainer's shoulders, as in that case there would never have been a stable
kernel version containing the MTD-based ps3vram driver.

- ps3vram-ng is faster than ps3vram:
o 1 MiB blocks: +50% (read), +5% (write)
o 4 KiB blocks: +50% (read), +5% (write)
o 512 B blocks: +10% (read), +10% (write)
Fwiw, it's a useful swap device, since space is so limited -- the
performance improvements are certainly appealing too.
