I'm planning to buy 2 ultra160 drives and set them as a bootable drive in raid 0 on a 64/33 atto card... is this possible to boot from?

Bootable RAID is a feature of the firmware in your machine, NOT the OS it's running.
Think about it. It has to boot before the OS is loaded, so it doesn't matter what OS you intend you use, the firmware in the machine has to know how to boot from RAID volumes.
Since you don't say which machine you're using, it's impossible to answer your question.
In general, all recent Macs (G4s on) are able to boot from RAID volumes built using Apple's Disk Utility and on the internal bus. If you're using a third party card you need to check with the vendor to make sure it'll work. Some will, but if the card needs drivers loaded during startup, you can't boot from it.

RAID 0 is asking for trouble unless you have a requirement for that much space in one volume, and, even then, it's still bad news.
Make sure you back up your data frequently, if not more often.

I will be... I've got a 40gig drive I use for backups and 120gig drive I use for data like mp3 and DV. This drive will simply be my boot drive and that's about it... If it fails I can always boot from the 40gig drive. The drives attached are both 9gig drives... not much room for anything else but a boot partition
