If it's nVidia, try building the driver with ACPI_PM enabled and running "acpiconf -s3" from X11. That boots the video chip up on my laptop at least - though it seems some corruption occurs because I've had some odd panics afterwards in the fs and vm subsystems, and attempting to suspend for a second time results in the system rebooting instead. -- Bruce Cran
