Thank you for your report.

Your forgot to put the following lines in device.hints.
hint.atkbdc.0.at="isa"
hint.atkbdc.0.port="0x60"
See /sys/i386/conf/GENERIC.hints.
However, there definitely are some strange things about
ACPI and PnP BIOS in your machine...
Your first dmesg: the acpi module is enabled.

The PS/2 mouse is detected. But, the AT keyboard driver
is assigned with port resources 0x64 and 0x60; the order should
normally be 0x60, then 0x64...
Your second dmesg: the acpi module is disabled.
As you don't have
hint.atkbdc.0.at="isa"
hint.atkbdc.0.port="0x60"
in device hints, the kernel tried to attach the keyboard
controller, keyboard and PS/2 mouse based on the PnP BIOS
information. This should normally work, despite the missing
above lines in device.hints, because the information
supplied by the PnP BIOS is supporsed to be correct. But, see below.

This is the PS/2 mouse reported by the PnP BIOS. It should be
assigned with the "irq mask 0x1000". But it's missing here!

>atkbd0: <AT Keyboard> flags 0x1 irq 1 on atkbdc0

(The above failure is expected, and you can ignore.)
>psmcpnp0: <PS/2 mouse port> on isa0
You should see
psm0: <PS/2 mouse> irq 12 on atkbdc0
psmcpnp0: <PS/2 mouse port> irq 12 on isa0
at this point. But, because the irq was not assigned to the PS/2
mouse node earlier by the PnP BIOS, the mouse failed to attach.
I have never seen this failure before ;-(
I will think about what I can do...
