ACPI sleep mode fix for Ubuntu boxes

Did some Googling and toggling: hope this works for the EEE PCs and old Dell boxes I've been working with. Intel video chipsets seem particularly vulnerable to this.

* Change sleep mode in BIOS to AUTO or S1

* Edit /etc/default/acpi-support to look like the following...

# Comment the next line to disable suspend to disk
#ACPI_HIBERNATE=true

# Change the following to "standby" to use ACPI S1 sleep, rather than S3.
# This will save less power, but may work on more machines
ACPI_SLEEP_MODE=standby

*EDIT: EEE PC didn't like that fix, but some USB card-reading keyboards stopped bugging out on some Acer Revo units I setup. Trying ACPT_SLEEP=false & ACPI_HIBERNATE=false on the EEE PC.
