Just FYI, a really really quick and dirty way of testing this sort of thing on more architectures and you're likely to physically have? 1) Install QEMU. 2) Grab http://landley.net/code/firmware (releases in the downloads directory, or tarball of most recent repository snapshot is wget "http://landley.net/hg/firmware?ca=tip;type=gz";). 3) Edit "download.sh" to point at the URL of your tarball instead of whatever kernel.org version it's using. (Or add your patch to sources/patches if it applies to the version it's already using. Note that if you set SHA1= blank in download.sh it'll skip the checksum test, so you don't have to recalculate the sha1sum if you don't want to.) 4) Run ./build.sh for the architecture you're interested in. (I suggest armv4l, i686, mipsel, and x86_64. Both sparc and ppc are currently broken for different reasons; I'm working on it.) Wait a longish time for it to finish compiling. :) 5) "cd build; ./run-armv4l.sh" and your shell prompt should now be in qemu running a kernel for the appropriate architecture. (You even have a native version of gcc you can build stuff with, although you may have to "ln -s /tools/lib /lib" to run the results, for reasons Linux From Scratch developers will recognize. :) This won't help you test real hardware (at least hardware qemu doesn't emulate), but for stuff like filesystems or executable file formats, it's handy. :) Email me if something doesn't work...
