APM on SMP kernel

[support-lists at petdoctors.co.uk (Nigel Kendrick)]

I'm Currently running Centos 3.4 on an old Dell PowerEdge with dual PIII-450
processors.

I know from searching that 'APM is not SMP safe' and so when I choose to
reboot the server someone has to hit the power button to power down and then
restart it. 

Most of the Web-based info I have found on APM and SMP is dated 2000-2002 so
can anyone update me on whether there is now any way round this to allow an
unattended reboot?

Thanks
