Wow. I keep finding more things wrong with this Intel machine. Now, if I plug in an external monitor (something I had not yet tried at home with my Cinema Display, but which I just tried now with a Princeton LCD19D flat panel display), I get a kernel panic. If an external monitor is plugged in when I reboot, I get a kernel panic. I've sent the crash report to Apple, but who knows if anyone will ever see it? Meanwhile, I'm now stuck without being able to use my big screens.
Here's the crash reporter info and the unfriendly message I sent along with it to Apple (I have no tolerance for crap like this):

How fucking charming. A 100% reproducible kernel panic if I plug in an external monitor. Is my brand-fucking-new MacBook Pro a fucking lemon? Does its external video hardware cause a kernel panic, or is it crappy software? I know you guys never seem to develop while regularly swiching monitor configurations, maybe no one there ever bothered to plug in an external monitor? Fuck.
If I plug in a monitor after boot, or if I have it plugged in during boot, the machine kernel panics.
And crashreporter's "Send to Apple" button is disable when there's no network connection, but there's nothing in the dialog to indicate this is why. It took me 10 minutes of wondering how I was gonna get this info sent to Apple to realize I had not yet gotten on the wireless network here at work (because the crappy Migration Assistant failed to migrate any of my preferred networks' information over).
