No LED Notifications

I can't get my LED notifications to work on GMail, text messages or Google Voice messages. I have text messages set up to blink red using both Handcent and Missed Calls and it still won't do it. There's no LED for GMail (though I don't see anything in options that allows you to turn it on or off) or Google Voice (it's set to blink in options).

I know it works because when I have a missed call it blinks green (and damn is that LED small!) though there's also no blinking while someone is calling (my OG Droid did).

Any ideas why this is happening??
