Looks like there's none,  at last in ata-3 (and my drive is definitively not
and ata-4). Looks like disabling the write cache is the only option.
I'll look at the ata-4 standarts (at work) tomorow morning.
However, I don't think this can hurt performances in a significant manner.
I'll let know the results here.
