Use hardware test mode directly on latest MacBook pro

On my 15" MacBook Pro (2.4GHz Penryn, February 2008), I've found I can boot into the hardware test mode without having the hardware test disc in the machine. If I press F2 before the startup bell, the machine directly enters hardware test mode. I don't know if this works with MacBooks or iMacs, however.

[robg adds: This doesn't work on my older MacBook Pro. I know that you can press 'D' at startup on the MacBook Air to get into hardware test mode, but this is the first I've heard of it on other models. (Any model should boot into hardware test mode by holding 'D' at boot with the install disc in the optical drive.) If someone else can confirm the no-disc-required behavior on a newer MacBook Pro (or other Mac), please post in the comments.]
