That's entirely possible.

I don't see any selection. I see this:

        Toolchain component options  --->
        --- Toolchain selection.
        ()  Enter any CFLAGS for gcc/g++
        --- Choose your Kernel
            kernel (Linux 2.6.24-mx)  --->
        [ ] Always rebuild the kernel

Yes, I have these entries.

Thanks, that's exactly it. I had added the platform, but then clobbered
it when I was moving around files and doing a cvs update.

Replacing with my edited version makes everything work again (well,
except for mtd-utils, which is a subject for another message).
