Paul Harrison has jogged my memory about another "gotcha".  IIRC, some
motherboards tie the BIOS setting for the APM RTC alarm function to the
ACPI RTC alarm function so either they're both enabled or both disabled.
Just to confuse everyone (I think ;-) others have them diametrically opposed
so that enabling the APM RTC alarm function effectively disables the ACPI
RTC alarm function and vice versa.  In short, you need to try tests with
both
states of the BIOS controlled APM RTC alarm function.  If you have no luck
with either state, then try them again with the reboot operation put into
effect.

IIRC, Matthias Hensler's webpage for Suspend2 under Fedora Core had some
discussion of how to work with motherboards that require reboots to get the
alarm to work.  See http://mhensler.de/swsusp/

Another place to research is the ACPI HOWTO created by Ariel Glenn at
Columbia University.  See
http://www.columbia.edu/~ariel/acpi/<http://www.columbia.edu/%7Eariel/acpi/>
At times, I found the text version to be better to work with and at others,
the
html version worked better.  I guess it depended on whether I was really
reading
the text or chasing the cross-references.

Perhaps some of these suggestions will help.

Craig.
