[~/GIT/linux-2.6]> grep CONFIG_ACPI_AC .config
CONFIG_ACPI_AC=y

[~/GIT/linux-2.6]> lsmod|grep ac
af_packet              19976  2
cpufreq_userspace       3732  0

But it looks like older kernels had only  /proc/acpi/ac_adapter/ADP1 and it 
worked fine with HAL, maybe something in sysfs changed? Also for some reason 
hal-addon-acpi doesn't seem to start at all, which might be the problem.
