 Well, the only thing that the current booted kernel filename is
 used for is in the check_free() routine; if you eliminate that,
 savecore works as expected. I'm somewhat tempted to just remove the
 func entirely, as these days it's difficult to guess what the size
 of the coredump + size of the kernel will actually be - especially
 if they're gzipped.
