This is entirely an initramfs issue/question.  The device should be
present in early userspace when it attempts to resume.  Also, s2ram &Co
may not be prepared for changing device name/node.

I've a system with only one "drive" being an usb flash stick (Sandisk
Cruzer Fit).  This system is able to hibernate and resume just fine,
but I don't do it often (it is our router).
