Review the lines that dmassage has commented-out. You can fairly safely remove unused drivers for network/scsi/audio controllers/USB devices, but other drivers/pseudo-devices are more likely to give problems. Trimming out devices (especially some scsi and nic drivers) will trim out a lot, and if you then find you need to go further, you'll just need to take it step by step with educated guesses. dmassage is about 12 years old, it is useful in some cases but the generated config cannot be used directly.
