Not really, for highly modular distro kernels. >I did a 15 minutes hack to try ripping the .c -> .s -> .o stuff out. Looks good to me.

The on-disk size of the modules in my builds is reduced by about 5% with this patch (but I can't immediately tell how much of this is due to __crc_* vs. other symbol stripping).
