If you add the "ATA passthru" patch (from Jeff Garzik) to your kernel, then hdparm can work with those drives.
Some flags, like "-d", are not supported by libata. Currently, ALL SATA hard drives use DMA, so there is no need for -d. But eventually libata will have to implement ATA PIO (for CF cards..), and at that time it may (or not) begin to support the "-d" flag.
