Thanks, Actually I think that stripped and LZMA'd it should make a
little less difference. If I get tight and willing to remove cruft I
know where I can cut off, and then I'll try to patch it unless someone
does it first. I'd appreciate more something that wouldn't compile the
kernel modules at all :)

Also, what is extboot used for? Can I ommit it from my build?

Regards,
Cristi
