Below is the rewrite of the PS3 Video RAM Storage Driver as a plain block
device, as requested by Arnd Bergmann.

The MTD-based PS3 Video RAM Storage Driver was integrated into the mainline
kernel in 2.6.29-rc1.

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.

What do you think? If this is accepted, I'll submit a patch to remove the MTD
ps3vram and add the new driver as ps3vram (instead of ps3vram-ng).

Thanks for your (review and other) comments!
