Your OLPC experiments, they are in an enviroment booted by LinuxBIOS right?
Yes. The test environment is booted directly from LinuxBIOS as a direct payload.
If so then its pointing more toward a driver issue rather than
a register config problem?
I wouldn't go that far; it could be a register config problem that is causing a driver malfunction.

My code is not using interrupts, but instead accessing the 8042 controller on a polling schedule that is under my direct control.

It could be that, for example, there is something wrong with the interrupt controller setup such that the Linux driver is not able to service the interrupts with the expected timing.
