Solid State drive in a G4 powerbook?

Why is my airport light blinking?

The most likely reason the airport is blinking could be due to a pending update.  7.5.2 needs to go to 7.6. If this is the case, then you’ll see a button to update to 7.6. Apple decided to cause the light to blink amber for this 7.6 update. Everyone’s airport routers are blinking.  However there could certainly be other reasons.  By opening airport utility and clicking on the status light the device will list the error(s) it's reporting.  Some errors are normal and can be ignored.  For instance, the error for default password for the device is fine.
