This one feature can make a big difference to whether your higher end
NForce Professional chips will even be considered for low/mid range
servers. Now that some NCQ support is starting to appear in libata,
people will be looking to elsewhere for motherboards that offer NCQ
support under Linux. If Nvidia had provided a binary driver, who knows
how many would now be using boxes that have NForce Professional chips?
