From my experience, this does not work with TP R50e.

If you want to be able to resume, you need :

* To start from a VT
* No option acpi_sleep
* to save the PCI state like:
 * cat /proc/bus/pci/00/02.0 > /var/cache/video.config
* Once you get back, restore it:
 * cat /var/cache/video.config > /proc/bus/pci/00/02.0

However, the X screen is not clean after the restore, so this is not very useable...
