On that note ACPI still locks hard both my laptops (ASUS/Acer) on 
resume, with and upto date -current its back to not even switching on 
the backlight, so I have no way to tell what happens. On the ASUS that 
has a serial port even that is totally dead.

However, commenting out the resume code in acpi_cmbat.c make it get so 
far as to give me a prompt in singleuser mode, but just a simple ls 
makes in crash with a double fault in the image activation of the ls 
command, it looks like the vm system is way out to lunch somehow.
