We have all our desktop PCs here set to bring the PC out of standby in
response to any network traffic to it.  A simple ping will wake it up.
 Though, these are all Windows boxes though and it's part of the power
management settings for the device driver.  I should try this out on
my laptop running Fedora over the weekend.  I've never bothered much
with power management on Linux since typically I just want the box to
be up and running. :)  I wonder if it's a function of the driver or
ACPI.
