Try adding "reboot=pci" to the kernel command line.  That fixed the
issue for me.  I'm running 2.6.30-gentoo-r1 (x86_64) on a late 2008
MacBook Pro.  Yes, I know it's not an Ubuntu kernel, but you guys appear
to be the only folks on the planet with an actual bug filed about this!

In my testing, reboot=kbd (the default) did not work, nor did
reboot=acpi, or reboot=efi.  I didn't try reboot=triple since a triple-
fault reset seems like an ugly way to recycle the system.  reboot=bios
might be another option if you're running 32-bit.

Bug description:
As of Jaunty (Ubuntu 9.04) Alpha 5, with kernel 2.6.28-8-generic, the MacBook 5.1 will hang upon attempts to reboot (restart). The screen will go blank black, and the system will hang indefinitely. I suppose this is an improvement over Intrepid (Ubuntu 8.10), where the computer would both hang and make very loud beeping noises. :-) Still, I'm marking this as a bug since reboot is currently not possible.
