We've asked about it. I presume that in the most recent versions of FW, that if they haven't made any adjustments for fixed it, I don't think there is going to be any thing done.
New router models are already out there and they have the new TS engines that have selectable higher Uplink speeds. That engine is based off of the DIR-645. Up to 10Mb currently for Users that have 10Mb ISP Uplink speeds.
It's possible that later versions of the 827 FW didn't use GPL code and may have been removed. You'd have to ask D-Link about this.
