There is no change, the systems all lock up hard on resume, on the two 
laptops (ASUS & Acer) the backlight doesn't even come on anymore....

Again reverting /sys/dev/acpica and /sys/i386/acpica back to aug 1st 
make things work (well almost, but that might not be ACPI's fault)...

This is a showstopper bug for 5.3 IMHO...
