setting up a single os software raid in ubuntu 8.04

Hello, I am trying to ditch M$*** for ever. The problem is that ubuntu 8.04 is not very user friendly at setting up either a fake raid 0, or a software raid 0. I have googled for 2 days, and can only find duel boot info. I do not want Windows on my system, but am beginning do give up and go back to the dark side. Can either a software raid 0 (mdadm), or a fakeraid 0 with the ich9r onboard be setup without a 3 hr setup process? I am not alone in thinking this is the new winmodem of the 2000's. But unfortunately it will only discourage people from making the switch and never looking back at linux again. Not a very good strategy of ubuntu to constantly refuse to support an easy fakeraid setup with each release. Just give people what they want even if they shouldn't have it! With competition like this, it is no wonder M$ can release a hobbled Os like vista. Sorry for the slight rant, but I am about to turn the pc off for good and go back to golf. Thanks.
