Here's a workaround you might try:
- setup another drive as "GRUB drive" (e.g. it could be a tiny USB
  flash drive).
- arrange for your BIOS/EFI to boot GRUB from that auxiliary drive, and
  then arrange for that GRUB to load your kernel from your SSD.

Brings me to another question:
if you boot with a live CD, then mount your SSD somewhere, then
suspend, do you get errors about the SSD when you resume, or does it
work fine?
