ARGH! Now that indeed explains things very well.

Attached is a patch to make LinuxBIOS support precompressed payloads. While the LinuxBIOS build system can compress payloads on its own, the OLPC build system benefits from delivering a precompressed (and size-checked) payload.

Although the patch modifies targets/olpc/rev_a/Config.1M.lb this has no effect on current OLPC buildrom because it checks out an earlier revision of LinuxBIOS. So it should be a safe to apply.

As a reply to this message, I'll post the necessary OLPC buildrom changes to make use of the new infrastructure.
