Removing/re-installing uswsusp didn't change the situation. Removing, of course, made it so the system didn't even try a "resume," re-installing left me back at the ~5 minute waiting before being given the option to skip resume. I'm not sure why the wait duration is ~5 minutes.
Probably unrelated, but: I also note that Grub is behaving differently as well. I can no longer pick options on the grub boot menu; my KVM flashes the selector. Likewise, I get hub/usbhid warnings right before the resume/libgcrypt message. I.e., i can't even test previous kernels or boot-time configure. I've not looked into configuring grub. Also, if it's relevant: I'm using stock kernel: $ uname -a Linux blackbox 3.9-1-amd64 #1 SMP Debian 3.9.8-1 x86_64 GNU/Linux and haven't change grub configuration.
