I get the same behavior on my X40 with 2.6.8.1 and the latest ACPI
patch. It does, however, resume successfully with 2.6.7 and ACPI
20040715. My plan is to wait and see if 2.6.9 fixes it and, if not,
start splitting up the changes between 2.6.7 and 2.6.8.1 to see what
broke it. There are some noises about this on the acpi-devel list, so
hopefully it'll get fixed.
