Marcelo:

2.4.27-pre3 still seems to have the acpi_fixed_pwr_button and
acpi_fixed_sleep_button changes in it, which oopses for me
upon module unload. Sergey Vlasov's response to my report is
attached. The original oops report is here:

If you don't have another fix for it, please apply the included
patch in order to back that out.
