Hi DS,

I have a t42p with both suspend to ram and to disk (swsuspend2) working
without problems, using the ATI driver (not open source) v8.16.6 (source
packaged for debian).

Although I had trouble getting suspend to ram at all initially, what I
did at the end was to install swsuspend2 (both the kernel and userspace
stuff) and then modify the hibernate.conf to use suspend-to-ram instead
of swsuspend when I press Fn-F4 or close the lid and used a modified
hibernate_disk.conf when I press Fn-F12. The only changes I've needed
are using vbetool (the hibernate.conf file includes that) and commenting
out some other stuff I don't remember.

Hope this helps,
Carlos

##############################################################################
### Choose your Suspend method. You currently have 3 choices:
###
###    suspend2            Software Suspend 2 (requires kernel patches from
###                        http://www.suspend2.net/)
###
###    sysfs_power_state   Uses /sys/power/state to suspend (activates pmdisk
###                        on kernels < 2.6.8, or vanilla swsusp otherwise).
###
###    acpi_sleep          Uses /proc/acpi/sleep to activate swsusp, or other
###                        ACPI sleep state supported by your machine.
###
##############################################################################

### suspend2 (for Software Suspend 2)
#UseSuspend2 yes
#Reboot no
#EnableEscape yes
#DefaultConsoleLevel 1
#Compressor lzf
#Encryptor none
# ImageSizeLimit 200
## useful for initrd usage:
# SuspendDevice swap:/dev/hda2
## Powerdown method - 3 for suspend-to-RAM, 4 for ACPI S4 sleep, 5 for poweroff
#PowerdownMethod 3
## Any other /proc/software_suspend setting can be set like so:
# ProcSetting expected_compression 50
## Or traditionally like this:
# Suspend2AllSettings 0 0 2056 65535 5
## Or even from the results of hibernate --save-settings with this:
# Suspend2AllSettingsFile /etc/hibernate/suspend-settings.conf
## For filewriter:
# FilewriterLocation /suspend_file 1000
# VerifyFilewriterResume2 yes
# ProcSetting userui_program /usr/local/sbin/suspend2ui_text

### sysfs_power_state
## To use /sys/power/state to suspend your machine (which may offer
## suspend-to-RAM, suspend-to-disk, standby, etc) comment out all the options
## above for Software Suspend 2, below for acpi_sleep, and uncomment this line.
## You may replace mem with any one of the states from "cat /sys/power/state"
UseSysfsPowerState mem
# PowerdownMethod shutdown

### acpi_sleep
## To use ACPI to suspend your machine (via /proc/acpi/sleep), comment out
## all the options above for Software Suspend 2 and sysfs, and uncomment this
## line. The number refers to the ACPI sleep state - 3 is suspend-to-RAM and
## 4 is suspend-to-disk.
#UseACPISleep 3

### Scriptlets
###   Scriptlets provide support for doing all sorts of things before and after

###   you may wish to edit these to taste. Consult "hibernate -h" for help on
###   the configuration settings.
