I wrote an Android app that uses android.os.PowerManager.reboot(), and I added <uses-permission android:name="android.permission.REBOOT" /> in my AndroidManifest.xml. However, when I run the app, it always throws the following exception:

java.lang.SecurityException: Neither user 10039 nor current process has android.permission.REBOOT. at android.os.Parcel.readException(Parcel.java:1247)

Is the anything I'm doing wrong, or does froyo have some problem with rebooting?

You cannot get this permission. Only system applications and applications signed with the same key that was used to sign the firmware will be able to get that permission.

Why do you need to reboot? If you tell the necessity of rebooting, then may be someone can suggest you a better way to accomplish the same thing without rebooting.
