I am having the same problem with my Shuttle FT61 motherboard, although 
I have not tried to disable ACPI... Until now I thought I just had a 
faulty keyboard, as my method to fix this was to unplug the keyboard and 
plug it back in after bootup.  When this happens, I see this in dmesg as 
the last line:

input: AT Translated Set 2 keyboard on isa0060/serio0

I am also having problems with my AUX mouse, as seen in message

Subject: 2.6.12-rc5-mm1 breaks serio: i8042 AUX port

Frank, are you having problems with your ps/2 mouse port as well?

I haven't spent enough time experimenting with this, as I thought it 
might have had something to to with my hardware / KVM switch.  Seeing 
Frank's message is the reason why I've decided to chime back in on this.

As a clarification, I have been having these keyboard problems 
intermittently, regardless of whether I'm using -mm or mainline kernel.  
I was NOT having this problem in 2.6.11  I wasn't having the psaux mouse 
problems in 2.6.11 either  .... I unplugged my psaux mouse from that 
machine before 2.6.12-mainline was released, so I don't know if those 
symptoms are still present.  (using USB mouse now instead).  I am 
currently in my office, so I can't test this right now, and I will be 
away for this weekend.  I'll be able to make these tests again come 
Sunday night/Monday.   ...and I will try it this time WITHOUT the kvm 
switch.
