Thanks to all this multiplatform stuff, the autobuilder has been building
nothing but Versatile Express kernels for the last 20 days.  That totally
explains why it won't boot.

The only thing I was told is to add the above two config symbols.  That
is not the complete story.  There's also other symbols which need adding
too.  It also looks like Versatile Express support _can't_ be disabled in
a multiplatform kernel, which is ludicrous.

And... fixing the config finally results in something that boots on the
SDP4430.
