[boost] Regression tests machines

I am managing some spare machine with reasonable performances and compiler selection that are basically underused at the moment (including various i64, AMD and PowerPC server blade) with both gcc and icc. I guessed they could be used to run the boost regression test on a dialy or weekly basis. I found out about the : http://www.boost.org/development/running_regression_tests.html page but I wanted to know if there is any speficic need in term of paltofrm/compiler coverage or if I can just run whatever and push the regression result up ?
