yes, they will work with the stock drivers - but for best performance and 
reliability you need to upgrade the firmware once the OS is installed. 

When initializing a raid 1, the controller wipes out all data according to the 
manuals. Every now and then you hear from people that say that the controller 
copies everything from disk1 to disk2 and if your IDE controller sector 
mapping matches what the 3ware controller does, you can keep your data in 
tact. Unfortunately noone can tell me what controllers would work and what I 
am doing wrong. I've tried that twice and it didn't work for me though, so 
from my point of view, what you want to do, isn't going to work...
