This leads me to ask:

I'm looking forward to putting MacOS 9.1, OS X, and Linux on my newly
purchased Tibook this weekend, and I'd like to ask up front, not having
messed with the newworld macs before, is it doable to set the machine up to
"triple boot" all three?  And in what order should I install the OS's, that
is, if I install Linux first, is there a possibility of MacOS X tromping
the boot loader or anything like that?
