What ACPI docs? There's nothing in the kernel Documentation directory.
linux/Documentation/pm.txt doesn't talk about it at all; the acpid man
page doesn't mention it, nor does /usr/share/doc/acpid, nor does
http://acpid.sf.net/
And the ACPI4Linux pages have moved and links to them have been broken
since I got the laptop a couple of weeks ago.

echo 1 > /proc/acpi/sleep
appears to do nothing.
echo 3 > /proc/acpi/sleep
puts the machine to sleep, but nothing I do seems to wake it up again?
cat /proc/acpi/sleep gives:
S0 S3 S4 S5
Looking at drivers/acpi/ospm/system/sm_osl.c it doesn't look like the
code to handle states 3 or 4 exist yet... it's all #if 0 in the
source.
