If you just want to get your bars up higher and you have a threaded headset, you can get a stem with a long quill and jack em to the moon. Nitto Technomics work great for this; they go up rediculously high. Go to the rivendell website and you'll see lots of them in action.

Also, switching to a genuinely ergonomic aero road hood instead of the standard aero "hand hatchets" makes road drops way more functional. This means Tektro/ Cane Creek/ Soma aero levers. They're cheap as all get out (<$40 for the tektros) and really increase the functionality of road bars. I actually rode around for 100 kms with one Dura Ace aero lever and one Tektro---for comfort there's really no comparison.
