Sorry, I didn't mean to be cryptic and it's really nothing deep. It's just that in the past Dave Miller used, let's say, "colorful" language whenever someone mentioned the fact that the original Itanium machines didn't have a hardware I/O TLB. The new Itanium 2 machines from hp have a chipset with heritage from pa-risc, so they don't have this limitation (to be fair to Intel though, I don't think the lack of a hw I/O TLB is a huge issue anymore, given that nowadays you can readily find all kinds of PCI controllers that support DAC, including network adapters).
