when /flash or /storage is on non-persistent storage, it's not
yet available at the time fsck -a -p fires, so just skip
and force fsck only if ret=4
now, if /flash or /storage is non-persistent, users get
either non-recovered fs (just as it was before) or debug
shell if the fs is fubar (bad sb and so). nobody cares.
Tweak to support the newer PS3 BD (with IR) remote which identifies differently.
