Pete,
I am a Debianite :) My Power button is managed by the ibm-acpi module to 
be associated with shutdown. I normally use to press the left Fn blue 
button for a second or so to wake up the creature

swsusp2 went smooth from the very first time I tried. Obvious questions. 
Are you using the correct version ? Are you sleeping onto your swap 
partition ? Is the latter as large as you physical RAM (in my case 1GB 
RAM and 1GB swap). Here are my settings for 2.1.5.15

# Software Suspend 2
#
CONFIG_SOFTWARE_SUSPEND2=y
CONFIG_SOFTWARE_SUSPEND2_BUILTIN=y
CONFIG_SOFTWARE_SUSPEND_SWAPWRITER=y

#
# Page Transformers
#
CONFIG_SOFTWARE_SUSPEND_LZF_COMPRESSION=y

#
# User Interface Options
#
CONFIG_SOFTWARE_SUSPEND_TEXT_MODE=y

#
# General Options
#
CONFIG_SOFTWARE_SUSPEND_DEFAULT_RESUME2="/dev/hda6"
# CONFIG_SOFTWARE_SUSPEND_KEEP_IMAGE is not set
CONFIG_SOFTWARE_SUSPEND_CHECK_RESUME_SAFE=y

#
# Debugging
#
# CONFIG_SOFTWARE_SUSPEND_DEBUG is not set

I have associated lid and Fn+F12 to swsusp2 and Fn+F4 to s3 sleep to 
RAM. hibernating is fast .. I would say around 10-15 seconds.
