Your kernel does not appear to have Software Suspend 2 support compiled in.
Please follow the HOWTO linked from http://www.suspend2.net/ for instructions
on how to compile Software Suspend into your kernel.

[root@dnote root]#
Broadcast message from root (Mon Dec 18 11:32:05 2006):

The kernel version "2.6.18-std-smp-alt2" in /boot does not match
the running kernel version "2.6.18-wks-smp-alt1". Resuming with
this kernel will not work. If you know what you are doing, you can
override this in /etc/sysconfig/powersave/sleep with the variable
SUSPEND2DISK_IGNORE_KERNEL_MISMATCH=yes.

Тут насколько я понял, что заработало нада саспендить из того ядра, которое 
прописано как /boot/vmlinuz. я прав? 

Далее
[root@dnote root]# powersave -u
Suspend-To-RAM has been disabled by administrator.

но 
echo mem > /sys/power/state  опускает таки машину в саспенд. 
ТОгда обьясните мне чем 
echo mem > /sys/power/state  
отличается от
powersave -u
если это команды одной программы
