Just FYI, for the PS3 bootloader we now use OpenWRT, which has kexec.
It is quite easy to use, and I think better than a custom config like
you have.
Jeremy Kerr has ported libtwin and his petitbooot to OpenWRT, which we
use, but those are not yet merged in. We have some local fixups we
plan to merge also.
