I would suggest a master's in some discipline of biology. Bioinformatics is the new buzzword among biology departments. Basically, if you can assist a department's researchers with datamining or creating the archtiecture to handle insane amounts of genome data, then you are set. The one caveat about getting into bioinformatics is to make sure that you actually understand the biological patterns you are dealing with on the computer side of things. Many, many bioinformatics meta-analyses yield results that have been known for many years but are new to the comp sci. crossover people. Also, try to focus your work on a sub-discipline of bioloy. For example, phylogentic theory and evolutionary data analyses have very different assumptions and demands than someone working on modeling neural pathways or signalling cascades. Become proficient in one biological domain to learn the big questions and departments would be willing to give you a look over others with less knowledge (we just went through this last spring with a job search, and I must stress that you need to know the biology!)
