Take a look at the details of how it's "not supported".  Hardware-wise 
the Promise cards, and most others like them, are a standard IDE 
controller and a bit of BIOS that lets you boot.  The RAID calculations 
are done in a fancy driver.  See if it's possible to treat the Promise 
card as a standard IDE controller and use the md software mirroring.  
I've found md to be much better than the Promise driver anyway.
