No psm with if_ath on current

I seem to hit lots of weird ones and this one is.

If I boot with if_ath loaded, my laptop does not find the mouse. If I
load if_ath after boot, everything seems to be fine.

I am running on a Lenovo T43 running current of 9/30. No APIC.

I compared boot-v output I found some big clues as to what is happening,
but I am far from sure if I am seeing a cause or a symptom.

First, the diff:

The kernel is loading at a different address and so are all modules. I
have no idea why of if this indicates anything.

acpi_timer is 1/1 without if_ath and 1/2 with it. This is totally
meaningless to me and probably irrelevant. I suspect the pcm diff is
also irrelevant.

The final one is acpi_ibm0. When ath is loaded, it grabs IRQ12 which
would normally handle psm0. If ath is not present, it is already tied to
psm0 and acpi_ibm lists no IRQ at all. Even without an IRQ, it seems to
work fine.

Can anyone suggest what might be going on here?

I'd be happy to provide other data if you can tell me what would help.
