Please use 2.6.7-rc1 as I requested.
All right. Here are results from 2.6.7-rc1. Not that they differ very much from what I posted before.
Actually in one critical way they did: on that 2.6.6 kernel, EHCI didn't resume correctly; it entered HALT state, due to some error. But on RC1 it came back correctly, as I expected.
Does USB still vanish on RC1? Based on what other folk have said, I'd expect it wouldn't vanish any more. And that it might even just work as you'd expect.
You do indeed have four different USB controllers on your system, even with just two ports (needing two or three controllers). Seems Intel doesn't remove them from their "mobile" chips, and your BIOS isn't disabling them ... so "lspci" shows them, and USB uses them.
