That's really the only one that springs to mind.

Given how simple a predictor would be, I think that's the best approach.

Setting the OS in the config file is a little tricky as in a couple of 
instances you'd want to know the exact version (linux moved the 64b direct 
mapped region at some point during 2.6 development).
