I would be very very careful with this. Supporting RAID under Linux does not gaurantee that it supports the same data layout as the drivers that you have. I do not know for a fact that it does not, but until you can determine that it does I would be extra careful. If you have a backup of all of the information that is current on the raid array then you might want to try to see if the Linux software is compatable with the current array, but if they are not compatble you could damage data in the process of doing this (thus the backup).
