It just hangs at the spinning pinwheel. I shut the machine off and booted it into Verbose-mode (Command-V) and it stops at "Initializing Power Manager" or something very early on. I pulled the battery and unplugged the machine, am letting it cool off (not that there's a point) -- it's one of the original MacBooks that had that "shutoff" problem with the wire that'd melt and short to the heatsink... but mine never had the issue because I wasn't using it very often at the time. Any ideas? The drive does show up when I hold down Option.
