Easy answer: make a copy of your special initrd, then turn off the immutable bit, then let dpkg do its thing and be happy, then replace the initrd with your copy and restore the immutable bit. Harder answer: probably edit /etc/kernel-img.conf and change the setting of do_initrd. But I've never tried that, so I don't know exactly what it does. At best, I'd imagine it might turn off *all* initrd creations, which would affect your *other* kernels too, not just this one.
