I just tried with
hint.acpi.0.disabled="1"
in /boot/device hints. The boot got this far through the process:
[...]
uhci0: <VIA 83C572 USB controller> port 0xc000-0xc01f irq 10 at device 7.2 on pci0
usb0: <VIA 83C572 USB controller> on uhci0
usb0: USB revision 1.0
uhub0: VIA UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered
and then hung. I left it for five minutes, no activity, and no response
on the keyboard, so I hit the reset button. For reference, the next
lines in the boot sequence with ACPI enabled are:
uhub1: Atmel Standard USB Hub, class 9/0, rev 1.10/3.00, addr 2
uhub1: 4 ports with 4 removable, self powered
uhci1: <VIA 83C572 USB controller> port 0xc400-0xc41f irq 10 at device 7.3 on pci0
usb1: <VIA 83C572 USB controller> on uhci1
usb1: USB revision 1.0
uhub2: VIA UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub2: 2 ports with 2 removable, self powered
[...]
