If it turns out that it's not possible to put symlinks into the initrd for some reason, another alternative would be to just pack /sbin/lvm, and to invoke it with the subcommand syntax. This is less convenient for a paniced admin than having all the symlinks available, but it's still a step up from the current situation with only /sbin/vgchange available.
The attached patch (not fully-tested) should implement this proposal.
