Actually, there is no such thing as configuration for the easy things.
Just make sure that the kernel doesn't try to use ACPI (boot with
noacpi boot option) and use APM. You can now use the "apm" program to
see battery information, Fn-F3 to switch off the backlight and Fn-F4 to
go to sleep. If sleeping doesn't work (some weird error beeps) you most
likely have to disable the PCMCIA driver.
For more information you should read the Power Management section of
your distribution's manual, e.g. to configure advanced features like
speedstep or APM scripts.
