"Asus Eee PC hotkeys stop working after prolonged usage"

I stuck at it, found a reliable test and bisected successfully. 
2.6.28-rc2 is broken, but I can fix it by reverting the bad commit. 
(There were some conflicts, I fixed up the dock driver manually and
avoided building the rest).

    ACPI: Change acpi_evaluate_integer to support 64-bit on 32-bit kernels

    As of version 2.0, ACPI can return 64-bit integers.  The current
    acpi_evaluate_integer only supports 64-bit integers on 64-bit platforms.
    Change the argument to take a pointer to an acpi_integer so we support
    64-bit integers on all platforms.

    lenb: replaced use of "acpi_integer" with "unsigned long long"
    lenb: fixed bug in acpi_thermal_trips_update()
