I agree, it was really slow :-(
Of course the booting depends on the hardware - disk, what filesystem is used, CPU speed, memory speed, what's in the kicklayout, etc.
By default everything is loaded in the kicklayout (to be safe), but you can remove many of the drivers if you will never use them to speed up booting and make more memory available.
I doubt he's had time to optimize it yet
PS - it does take some time to execute the x86 bios emulator for the Radeon initialization, that can add 5-30 seconds to the boot time, depending on your processor speed.
There is a difference from the slowest speed blizzard PPC to the fastest speed Cyberstorm PPC, of course.
