I'm guessing this is the reason that Apple had patented that WGA-style checking system to make sure that OS X is running on actual Apple hardware only. I'm sure it would make it much more simple working with pretty much the same internal hardware (now supporting EFI) to get Leopard up and running.

Wonderful, more FUD-ridden anti-Apple slander...

Just like that doom-mongering over the TPM chip on early Intel Macs that was going to shackle us all to our desks and make us eat gruel until Apple... oh took it out...

As for Gateway doing this before SP1, there might be a feature that allows for PC BIOS emulation to still support older versions of Windows prior to Vista SP1, as well as some older open source operating systems that still are not including EFI support. PC manufacturers are probably rolling out the system with EFI to be ready for when Vista SP1 rolls out.

It can't exactly be hard, Apple have had it working for almost 2 years now. All you need is an intermediary boot loader in the EFI firmware ROM. PCs with true 64-bit and EFI should have taken over years ago, but alas this is what you get for being part of the most held-back sectors of tech industry in the world [] ]'>
