I haven't had time to test your patch unfortunately but just wanted to let you know of a corner case to be aware of. To suspend, ACPI maps in and identity page table (phys == virt) and switches to real mode. I'm not sure if your patches change the ability to access the first 1M or change the way such a mapping would be done, but it would be useful if you thought about this. The code is in /sys/i386/acpica/acpi_wakeup.c: acpi_sleep_machdep(). Thanks, -Nate
