Well I don't know if that game is of similar requirements, but I've just borrowed Fallout 3 from my friend and launched it. It plays quite smoothly on medium settings. So maybe it's not so bad as you predict, however I may be wrong. If you know any games with similar requirements with downloadable demo and they don't require Pixel Shader 3.0 I could check them. As I stated before I don't play games nowadays so I'm not familiar with the new titles.

Fallout 3's requirements are substantially lower than Grimrock's. Grimrock's are more like Skyrim's.
Regardless, such comparison's are hardly worth putting much stock in. Different engines stress different things and scale in different ways, so it's almost impossible to predict how one game will perform based on another unless they share a substantial amount of their architecture.
The best test you're really going to get is just seeing how the game runs for others that don't meet the minimum requirements (don't worry, there will be tons of them on forums complaining that they were somehow "robbed" because they shouldn't be expected to read system requirements and all software should magically run on all computers).
That being said, I would think it's going to be quite a long time you're waiting before SM2 support would even be on the radar so I wouldn't worry about relative performance comparisons too soon. There's one coder on this project and they have a lot of sales-producing things on the To Do list for him already. 7-year old GPU support is going to be low on that list unless it turns out to be a very trivial thing to change.
I wish you the best of luck, but I honestly just don't want you to get your hopes up too much. Your computer is simply very far below the system requirements (regardless of SM3 support) and I suspect you will be disappointed to find that it doesn't perform well enough to be enjoyable even if it becomes functional on SM2 hardware at some point.
