And noapic especially severely limits your computer... no advanced irq mapping or routing. For a server it is a no-go option, for a desktop it might be a temporary workaround.
If noapic and/or acpi=off solves a problem, it is just a help to pinpoint the problem, it is not a solution. The solution is to get the manufacturer to fix their broken bios.
Speaking of that... maybe OpenFirmware would be a solution? Never tried it myself on x86 class machines. Anyone with any experience?
