Highpoint 2320

I have a Highpoint 2320 raid card that was running on a 11.3 machine. The main drive crashed.
Seems there are no drivers for the 3.4 kernel.

Is it possible to install a 2.6 kernel in 12.2 to get the data from the raid?
Or should I install 11.3 again to get the data?

Not sure if I want to buy a new Highpoint card or buy a card from some other vendor.
