I have the same situation, and if I hold ESC or some key just after
the bios screen has gone away, it brings up the grub menu. That's with
grub-0.97, which may be different than what you have.

The reason it's done, though, is so you don't do a full boot and blow
away all your data in swap.

You can blacklist the hook. Something like:

echo 'HOOK_BLACKLIST="99Zgrub"' > /etc/pm/config.d/blacklist
