If you can get another motherboard (or standalone PCI card) that uses a SIL3114 controller, then yes, you can just plug the drives in, and it should recognize the RAID-0 array.
If that's not an option, then you're looking at data recovery. I recommend RAID Reconstructor
by Runtime. (Same people who make GetDataBack for NTFS
It's reasonably inexpensive and I've tested it on a controller-less 2-drive RAID-0 and retrieved all the data.
