FWIW, prior to that boot I redid update-grub and update-initramfs in the hops it'd "fix" something. Everything stayed the same.
Just to make sure we're on the same page: /dev/sdq2 *IS* my root partition (normally, and right now). It's not that sdq2 was fetched out of thin air. On my MacBook Air with a freshly installed Kubuntu 12.04, the behavior is the same, although here root=/dev/mapper/sda6_crypt, both in GRUB itself and /proc/cmdline. I don't mean to sound wise-assy, but did you try cat'ing /proc/cmdline on your own install? Or hitting 'e' in GRUB to see what root= says there?
