Indeed,
adding

ehci_pci

to /etc/initramfs-tools/modules and running

update-initramfs -u -k 3.7.0-rc5+

to get /boot/initrd.img-3.7.0-rc5+
of the formerly broken -rc5+ build corrected
manages to fix boot.

Wouldn't have...
ehci-pci is the new top-level depender on ehci-hcd, not the other way
around.
Unfortunately such a change is even more insidious since one cannot pick
up the change in an automated manner (via dependency inspection).

A more automated yet KISS solution for initramfs dependency stuff would
be desireable if perhaps unfeasible.
