Hello,

Here's again the resume-finish-split patch, this time CC-ed to Len.

This patch splits up acpi_pm_leave. It introduces acpi_pm_leave which calls 
acpi_leave_sleep_state and acpi_disable_wakeup_device before resuming the 
devices. This improves S3 resume on an Acer Travelmate 800 and on the Samsung 
P3 notebook.

Some archive references:

The background is that any write access to the pci config registers of some 
devices(sound card, usb 2.0 controler, and modem) cause a system lockup if 
they are called before acpi_leave_sleep_state and acpi_disable_wakeup_device 
were called. This is on an Acer Travelmate 803 Notebook, and it seems to be 
the same on other systems.

I sent the patch to the list, but it seems that nobody noticed it and I forgot 
to send it again. Here is an updated patch against 2.6.10. I can't promise 
that it doesn't break other systems. Someone should make sure that 
pm_ops->leave is set to NULL for apm. I haven't found this in the apm code 
yet.

Cheers,
Stefan Dösinger
