        noacpi          [IA-32] Do not use ACPI for IRQ routing
                        or for PCI scanning.

        acpi=           [HW,ACPI] Advanced Configuration and Power Interface
                        Format: { force | off | ht | strict }
                        force -- enable ACPI if default was off
                        off -- disable ACPI if default was on
                        noirq -- do not use ACPI for IRQ routing
                        ht -- run only enough ACPI to enable Hyper Threading
                        strict --  Be less tolerant of platforms that are not
                                strictly ACPI specification compliant.
 
                        See also Documentation/pm.txt, pci=noacpi

It might also be worth temporarily disabling both sound and networking:
try commenting out the appropriate lines in /etc/modprobe.conf or
setting alias sound off.

It might *also* be worth playing with kernel.org kernels.

Hope this gives you a couple of ideas...
