I noticed that switching to nrv2b compression alone will save >20 kb. And nrv2b is already supported by LinuxBIOS.

If you apply the attached patch and change line 7 in work/linuxbios/LinuxBIOSv2/targets/olpc/rev_a/Config.1M.lb to

option CONFIG_COMPRESSED_ROM_STREAM=1

you _should_ get a working ROM.

Can someone please test this, preferably not on the builtin flash (in case it doesn't boot)?
