This has been my experience as well... Coming out of deep sleep to a blaring alarm clock is about the worst case scenario. If I can get natural light or a vibrating alarm to "warn" me, I'm much more receptive to the strong alarm and able to become alert much more quickly.
Right now, I don't have much control over ambient light, but I'd like to find a solution. I think that probably means automatically opening window shades in the summer (anyone tried this?) and, since I live in Seattle, a 10 KW spotlight rigged to a timer in the winter...
