would Promise SX6000 controller work under 5.1?

[alex]

Hi ppl!

I've a FreeBSD box with Promise TX2000 UATA controller and RAID0 array 
on it.
It works good.
But not long ago I've lost some importaint data because of disk failure. 
(Jesus last years HDDs are getting worse and worse)
So I decided to change for SX6000 that can handle RAID5 in IDE array but 
didn't find it in official hardware compatibility list.
I have no idea if Promise uses some kind of generic command set like 
Nvidia for TNT or GeForce and hence I need no worring or not.
So can anyone estimate if it works or not ?
