I have had that happened on the X40, strange thing, it doesn't happen 
when the I close the lid everything goes fine, as long as most of the 
modules are rmmod'ed from the system with the script that ACPI calls, 
like usb, bluetooth, atheros and the such

I can send you a copy of the script directly upon demand, to avoid 
trashing the list

this has not happened to me, you could try upgrading the firmware, 
there's some information about this at www.thinkwiki.org
