yes i believe you can djhash. My wife received government aid for school while she only had a green card. The conditional should not matter. As long as you have permanent residence status, you should be good.
I also found this information from another forum
Federal, state, and institutional aid includes: Federal Perkins, Stafford and PLUS Loans, Federal Pell and SEOG Grants, Federal Work Study.
To be considered for federal, state, students must be at least one of the following:
~ United States citizen (native-born or naturalized).
~ U.S. national (includes natives of American Samoa or Swain's Island).
~ U.S. permanent resident. Must have an I-151, I-551, or I-551C (Alien Registration Receipt Card), or a Passport or an I-94 Form with a stamp indicating I-551 status.
~ Eligible Non-citizen with an INS Arrival-Departure Record (I-94) Form with one of the following designations:

Students holding only the following Visas are NOT eligible for any federal, state, or institutional financial aid:
