Am I still eligible for the $8,000 first-time homebuyer's tax credit if I buy through FHA?

I'm a resident of Machusetts and we have some first-time home buyer programs that will either give grants or subsidize interest payments through a "soft-second" loan to help curb having to pay PMI. If I take advantage of either one of these, would I still qualify for the $8,000 tax credit that's part of Obama's stimulus package?
