It does, correctly, identify the keyboard and mode port, so it's
somewhat odd that it doesn't get used...

Indeed. The only other observation in the older kernel that works
it detects the AUX port first.

Booting with 'i8042.debug' will spit some more output into dmesg, which 
might help us to see if i8042 is really properly initialized, or something 
strange is going on during initialization.

Please find below the new dmesg created by appending i8042.debug; this was
taken from a slightly newer build of the same source kernel that I reported; this
build just had a few more things configured out (parallel port) but exhibits
the same symptom.

<old dmesg removed>

Is there any change if you boot with 'i8042.noaux' kernel command-line 
parameter?

Yes, with i8042.noaux it works; dmesg snippet included below.

And in reply to hpa, it doesn't have a mouse port.
