This is not really a fatal error for the entire build. The default make target will build both a vmlinux file and a .bld file. The .bld file is the one that can be programmed to the OtherOS flash memory (bld = boot loader). Even if the .bld file is too big, a big vmlinux file from such a build would be completely fine for petitboot to load. It may be good to print an 'info' message though. I'll post an updated patch. -Geoff

The ps3's otheros flash loader has a size limit of 16 MiB for the uncompressed image. If that limit will be reached output the flash image file as 'otheros-too-big.bld'.
