One of the things I'm interested in knowing is if you force the grub menu to displayed every time you boot (so any non-zero value of GRUB_TIMEOUT) does the hang happen before the boot menu is displayed. If so then it's pretty conclusive that it's happening in grub. Based on your comments I'm thinking that's probably the case.
