There are no worthwhile alternatives really. EECH or LB2 are still the best choice in my opinion. If you think its your Laptops GFX card that stops you playing EECH, then perhaps you should try EECH2, other than that wait for DCS:BlackShark.
BTW did you try turning on the 32 bit option in the eech.ini on your laptop. I recently had an issue getting EECH to run with a new core duo with integrated graphics. In the end i just turned on 32bit in the ini and it ran fine. I figured the new GFX choked on the default 16bit option.
Good Luck

ps- Armed Assaults XAM helo's are fun to fly low through the terrain, but theres no cockpit systems making it an arcade shooter in my view. The background radio comms traffic is excellent though.
I feel your pain, EECH rocks
