So they basically violate the standard and transition to S4 without telling the OS, then jump to the S3 wakeup vector, so it thinks the system was in S3 the whole time?

This other document I found here:

Says that the software takes steps to reduce the set of pages that must be saved. Is there an as yet undescribed acpi method to send the bios a memory usage map before entering S3, and it defaults to saving all of system ram under Linux, which would make it slower than software hibernate?
