When I  played through Suikoden the first time, Gremios death came as an big hit in my belly. I acctualy cried.
Since then I have tried to resseruct him. And now I have succed. Okay, it whas 6 months ago, but...
Do this.....
Get all the 108 Stars of Destiny before the last battle. No one is allowed to get hurt or die in a major battle. Then, when you decieds to go in battle with the Imperial Army, Leeknat will appear. She will use the power of all the Stars of Destiny and her "back" rune and brings Gremio back.
