I will try that. I can manually remove all usb related modules, but not 
usbcore.

No, after S1 resume I have to keep the power button pressed for some 6 
sec to power off the laptop.

How? I don't know were to start.

I have compiled the kernel with CONFIG_ACPI_DEBUG, but I don't know how 
to use it. What shall I "echo" to /proc/acpy/debug_layer 
and /proc/acpy/debug_level, in order to debug this standby/resume 
problem? Remember that as soon as resume happens the laptop hangs, and 
nothing is written to the system logs (only to the screen) -- can we 
force syslog to circunvent the disk buffer/cache?

I dont' configure apic in the kernel, as it used to give problems in my 
laptop.

No. I have tried all 2.6.x kernels, but all they fail. 
I will try and I report latter.

Thanks,
