This seems to be a somewhat common problem; see e.g. 

     http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=373660

Anyway, the only workaround that I know about is to add a line that
actually suspends the laptop for you. I replaced the call to
acpi_fakekey with 

/etc/acpi/sleep.sh

(for details, see
http://www.cs.unb.ca/~bremner/blog/suspend-to-disk-key.html)

Note that this may interfere with gui powersave tools like kpowersave.

By the way, in the future please tell us what distribution of Linux
you are running. Much of the acpi support happens outside the kernel.
Even the kernels are typically customized by the distribution.
