I can S3 suspend from X (provided you correctly supply acpi_sleep=s3_bios on the boot command line) , without unloading any modules and restore works like a charm. But maybe you are confused about the model number as the L3800C has a Radeon M7... (or maybe newer version have an M8). The only remaining problem on this laptop is that without patching ACPI code, upon resume, ACPI buttons are dead. But you can still suspend calling the stript explicitely...
