There should be an option of where modules_install puts stuff.
<plasmaroo> Luke-Jr: For the makefile one I need to know what to pass to the kernel Makefiles. <plasmaroo> Luke-Jr: I'll have a look at both tomorrow. <Luke-Jr> k.. I'll look at what needs to be done for that <plasmaroo> Thanks. <Luke-Jr> done =p <Luke-Jr> make modules_install INSTALL_MOD_PATH=/tmp <Luke-Jr> makes /tmp/lib/etc <Luke-Jr> (etc being English etc, not the literal text) <plasmaroo> Ah; cool. I can add that. <Luke-Jr> I guess that'd be --module-root <Luke-Jr> or --root and use it for /boot too <plasmaroo> Hm. Sounds good.
Just use '--no-install --module-prefix=<tempDir> --tempdir=<tempDir>' with 3.0.2e - the kernel and system map will be dumped into $tempDir and modules into $tempDir/lib/modules/...
