The most common case for S3 problems is a dead screen and a dead keyboard +
mouse, which results in a supposedly non-responsive system (the NIC is
usually fine, but then you need a second machine to check that). Since you
wrote about hard reboot, I assumed you tried ctrl+alt+del and it didn't
work, hence the keyboard problem.

Then you're probably out of luck for now. You may, as Pavel suggests, try
suspending from X, but it probably will reboot if you have AGP drivers
loaded.
