I replaced the drive with a 250GB one (bigger and cheaper than an exact "Death Star" replacement from an Apple dealer), then restored from TimeMachine backup (pretty slick, actually), and am now trying to figure out what is broken.
- Fink stopped working, but probably due to me being stupid (found an error in a config file, and easily fixed Fink)
- Had to reinstall developer tools.
- Needed to perform software update twice before mail worked
Other than that, time machine saved my butt. Now to recreate the last week's worth of work, and to convince myself to do daily backups instead of weekly ones.
