If dmesg says
Code: | ACPI: Unable to locate RSDP
ACPI: Subsystem revision 20041105
ACPI: Interpreter disabled. |
could that mean that my chipset or whatever doesn't support ACPI (fully~?).
If not, I'll go with APM

Almost no system supports ACPI fully - the standard is too complex and most implementations are a total mess.
By all means, go with APM if it does what you want.
But note that ACPI does more than power management - it also takes care of boot-time IRQ routing and PCI plug and play and the like.
I usually simply try it and when it messes up, I get rid of it again _________________ >>> emerge (3 of 7) mcse/70-293 to /

Ah, got it fixed, I just had to hex edit some new bios.
Now, what fun things can I do with this:
Code: | # dmesg | grep ^ACPI:
ACPI: RSDP (v000 PTLTD ) @ 0x000f6e90
ACPI: RSDT (v001 PTLTD RSDT 0x00000000 PTL 0x01000000) @ 0x040fdc09
ACPI: FADT (v001 INTEL ATLANTA 0x19990416 PTL 0x000f4240) @ 0x040ff78c
ACPI: DSDT (v001 Intel Atlant 0x00000000 MSFT 0x0100000b) @ 0x00000000
ACPI: setting ELCR to 0200 (from 0a00)
ACPI: Subsystem revision 20041203
ACPI: Interpreter enabled
