With your patch applied the default for ACPI systems changes from
HIBERNATION_PLATFORM to HIBERNATION_SHUTDOWN. However,
it has been HIBERNATION_PLATFORM since 2.6.20 and I'd really
prefer it to stay this way.
If HIBERNATION_PLATFORM doesn't work for you, please do
"echo shutdown > /sys/power/disk" before hibernation or, if you use the
userland suspend tools, change the s2disk's configuration file to use the
"shutdown" mode.
