    Probably I didn't post them. What I posted was a small subset of the full log.

    Not all the way up to the new menu, but before the bits that depend on them,
    which are in drivers/video/ drivers/media/video and drivers/ieee1394 IIRC.

    I'm hoping to have an RPM out this weekend so you can do the augury yourself.

    Apparently. In the stock kernel:

    warning:arch/mips/config.in:224:"CONFIG_KMOD" has overlapping definitions
    warning:init/Config.in:19:location of previous definition
    warning:arch/parisc/config.in:53:"CONFIG_KMOD" has overlapping definitions
    warning:init/Config.in:19:location of previous definition

    Did I mention Gordian knot?

    There's two in the same file, lines 185 and 189.

    Please ignore that one. It's an artifact of the way I check for symbols
    not declared anywhere at all, related to config.in's using the same banner
    for a menu and a comment.

    Greg.
