The problem seems to be that CONFIG_ACPI_PROCFS_POWER is not set

Currently most acpi packages[*] use /proc/acpi/{battery,ac}/...
to get the power status. This usage is deprecated in 2.6.24
and so Debian kernels would probably need to enable this feature
or bugs should be filed against all such packages.

Kapil.
