Basically you roll the complementary skill (i.e. Security Systems Knowledge for an Electronics Test to get past a maglock), and every two successes grant an additional die for the actual test.
In SR4 this could be used pretty much the same way, with every two hits on the complementary skill roll granting one additional die for the actual test.
Of course, the use of complementary skills should be reasonable (no Anatomy Knowledge for Firearms

This is a great way to actually make use of those Knowledge skills, I think, and allows to further differentiate between various character types.
