Tiger on HP

Given all of the hype around BootCamp and Parallels on the Mac, to allow the running of XP/Vista on Mac hardware, I started to wonder if the reverse was possible, i.e. running the Tiger OS on my trusted DV6000 from HP.  Why you may ask would I want to do this, firstly because I like my HP, secondly battery life on my HP running Windows is approx 5 hours, but on the Mac it is about 2 hours, and no extended battery can be purchased, and finally because I do not want to buy another laptop, I already have too many to count, and do not want to buy yet another one.

Reseach on the web, has not provided any information, perhaps I am asking the wrong question, so I decided to talk to an Apple employee at one of their stores.  It seems that I was the first person to ask the question, ( I find this hard to believe ), the tech support guy in the store was a little suprised I asked my question, and came up with the following reply ( this is summariezed version  )

Tiger will only run on hardware that has a special type of memory chip, the OS looks for the tweak and will only run if this tweak is found.

Take this for what it’s worth, a little more digging is needed I think, and perhaps a little experiment of my own, does anyone know where I can get a copy of Tiger for free ?
