4.5 Configuration of the Powermanagement

Since I use the Stylistic LT C-500 in my car I need the possibility to quick start and shutdown. APM provides this feature.

With kernel 2.4 (installed with SuSE 8.2) I had - beside trouble with sound, quite some problems with the powermanagement. Either the system did not wake up from hibernation (ACPI) or USB did not work afterward (APM). So I decided to change to kernel 2.6 after it's release, which instantaneously solved the sound problem, but left me still puzzled with ACPI/APM.
This situation cleared up after the upgrade to kernel 2.6.5 and I could use APM as planned.

Howto upgrade to kernel 2.6 is described in several sources and should not be the subject of this document.
I use this config.gz file, which is optimized for my periphery (WLAN, GPS-receiver), thus, if want to use it, you might need to do some adjustments. Finally I tuned /etc/sysconfig/powermanagment to configure the apmd to my likeing, by setting
APMD_SUSPEND_ON_AC="yes"
APMD_PCMCIA_SUSPEND_ON_SUSPEND="no"
APMD_PCMCIA_EJECT_ON_SUSPEND="yes"
APMD_INTERFACES_TO_STOP=""
APMD_INTERFACES_TO_UNLOAD=""
APMD_STOP_SOUND_BEFORE_SUSPEND="no"

Currently I try to find a solution to restart the GPS-demon after hibernation automatically after USB is restored, so gpsdrive does not stop working...
