In my exerience w/ the hpt27xx driver on 9.1-R, the card is terrible...
Caused me no end of pain.. I replaced the card w/ an ahci native card
(since I was hooking up SATA drivers), and now I'm happy...

I couldn't get any support from Highpoint... Not really surprising
considering the binary driver...
