Do you mean you're willing to put out 2.0-RELEASE with non-functional PPPoE on all x64 platforms? If I had to choose between PPPoE or PPTP support, that's a no-brainer for me: PPPoE is far more important. If PPTP doesn't work, I can put a PPTP server behind the pfSense box and tunnel through. If PPPoE doesn't work... I have to replace the firewall. Assuming I took your response correctly, the workaround would then be: run the i386 build instead. In my experience 32-bit code now provides about 20% less peak bandwidth than x86_64 code on the latest Xeons (don't know about Opterons). That's not a very good workaround, IMHO. (Yes, it's possible that was a hardware-specific result, I wasn't doing scientifically valid benchmarking.) And yes, I also realize it's unlikely I'll be pumping 10Gb/sec of data through the same router that needs to talk PPPoE to an ISP, so maybe no-one cares; the 32-bit build runs about as fast as the 64-bit build in normal cases. I wonder if there's some difference in DMA coalescing, or interrupt handling, in the device driver? For all I know the CPU could be running slower, or IOAT could be disabled or something like that in 32-bit mode. I'm only talking about a single data point here.
