In the last few weeks, my car has developed a new noise.

On a cold start, there is a squealing sound from the engine bay... sounds a little like a quieter version of a fluid-starved power steering pump with the car on the lock stops.
The noise seems to minimize at idle (~500-700rpm), but as soon as I bump the RPM to ~1000 or above, the noise returns and seems RPM-sensitive (the sound changes with RPM).
The squealing sound persists regardless of clutch position (although the sound sometimes fluctuates a bit as the pedal is being moved in or out).
I poked my head around the engine bay trying to figure out where the noise was coming from but couldn't locate its origin. My mechanic at a local shop put the car on a lift and said he though it was coming from the clutch and said it sounded like a throwout bearing.
The noise lessens as the car warms up.

I've got a call in to the nearest dealer (an hour away, unfortunately)... hopefully I can bring the car in soon. I've also noticed that the clutch fork squeaks when the clutch pedal is moved. Hopefully Subaru will warranty it, I guess... maybe it's a good time to do a lightweight flywheel?
