To make life easier I pulled in "next" GIT branch of Len's tree this
morning on top of upstream git829f51d.

My kernel built on the family Ubuntu box runs nicely means several
resume/suspend cycles were OK (see attached dmesg).

The only thing I was wondering is that CONFIG_ACPI_PROCFS_POWER is
still present as it should be removed with v2.6.39 (see below P.S.).

[    0.720019] ACPI: Deprecated procfs I/F for AC is loaded, please
retry with CONFIG_ACPI_PROCFS_POWER cleared
[    0.732591] ACPI: Deprecated procfs I/F for battery is loaded,
please retry with CONFIG_ACPI_PROCFS_POWER cleared

CONFIG_ACPI_PROCFS_POWER=y

Beside this "cosmetic" issue I can say this kernel runs OK for approx.
one day (~18hrs).

Hope this feedback helps to get ACPI stuff pulled into v3.5-rc1.

[ drivers/acpi/Kconfig ]

config ACPI_PROCFS_POWER
        bool "Deprecated power /proc/acpi directories"
        depends on PROC_FS
        help
          For backwards compatibility, this option allows
          deprecated power /proc/acpi/ directories to exist, even when
          they have been replaced by functions in /sys.
          The deprecated directories (and their replacements) include:
          /proc/acpi/battery/* (/sys/class/power_supply/*)
          /proc/acpi/ac_adapter/* (sys/class/power_supply/*)
          This option has no effect on /proc/acpi/ directories
          and functions, which do not yet exist in /sys
          This option, together with the proc directories, will be
          deleted in 2.6.39.

          Say N to delete power /proc/acpi/ directories that have moved to /sys/
