Actually, for "Problem #3", you don't need apmd or acpid installed and 
running, system poweroff is handled entirely by the kernel.

That being said, I believe the laptop in question does not have APM support, 
only ACPI support. Most distros turn off ACPI support, as it's not entirely 
implemented in Linux. I'm not sure about SuSE 8.1, but I know that SuSE 8.2 
does not turn off ACPI support (look for kernel boot parameter 'pci=noacpi' 
or 'acpi=off').

Also, that laptop may have a broken ACPI implementation, but it is possible to 
fix that yourself. Read http://acpi.sourceforge.net/dsdt/index.php for more 
details on that.

(Problem #5) Also note that with linux kernel 2.4.x, it is not possible to 
suspend/resume properly with ACPI (but I believe it works with APM, could 
someone else verify this?). Sleep/standby reportedly works fine by both APM 
and ACPI-enabled machines that support sleep-modes (ACPI mode S1).
