Please provide the output of 'sysctl hw.acpi.supported_states' to see if 
the machine supports S3 at all. The NetBSD kernel does not currently 
support S4.

Does the system support Speedstep?

tlp needs to be converted to PMF before the system will attempt to suspend.

This system is probably too old to have an I/O APIC, I wouldn't worry 
about it.

Again, these need to be converted to PMF. ioapic handles capturing and 
restoring IRQ routing on modern laptops, but we need to use 
acpi_pci_link on older ones. Our acpi_pci_link code doesn't attach as a 
device driver to the ACPI device nodes as it should, and PMF needs a 
device_t to be associated with a power handler.

You might want to capture/restore this state in acpi's PMF handler 
directly as a workaround.
