atkbdc broken on current ?

[aconnolly08 at yahoo.co.jp]

I've installed 9.0-RC3 on an Acer Aspir One net book and with acpi enabled atkbdc (and atkbd) are not loaded at all. I can use a usb keyboard with no problems, but once I've selected my boot options the integrated keyboard stops responding. The fix mentioned in this thread does not address my problem.
 
Any suggestions as to what steps I should try next?
