The canonical way to attach a pseudo device is via config_attach_pseudo(),
you could either make cgd(4) call it directly or investigate callers
of pseudo_disk_attach() and see if it makes sense to attach a pseudo
device from therein (I'm not familiar with the disk code, so this
is just an idea of handling all pseudo-disks in one shot).
