You mention that you have tried different ACPI options, but have you
tried booting with ACPI turned off entirely (acpi=off on the kernel
command line)?  At least as recently as 2.6.18 there were some HP
laptops that would overhead when ACPI was enabled.  I don't remember
your model being one of them, but it may help.
