Comment (by edglex):
I've done some more digging. It isn't exactly the same problem as ubuntu
(not sure how/if it relates to e820 and ACPI CRS) but it does appear to be
related to memory allocation. I turned on lots of tracing, and with ACPI
disabled (EHCI works) I get the following:
{{{
...
usb ehci -1: constructing new EHCI host controller driver
usb ehci -1: map physical memory 0x942c4000
add_memory_type_range(148, 0x942c4000, 0x1000, 0)
usb ehci -1: mapped capability registers: 0x0x81d2b000
usb ehci -1: mapped operational registers: 0x0x81d2b020

usb ehci -1: the host controller is bios owned, claiming ownership
usb ehci -1: controller is still bios owned, waiting
usb ehci -1: successfully took ownership of the host controller

}}}
And with ACPI enabled (EHCI not working):
{{{
