acpi and rh9-2.4.20 version

[Tapas Ranjan]

Hi :
	
I have a 2.4.20-31 RH9 version system, which doesn't support "acpi". 
As per my search , it's a bug in most 2.4 version kernels. 
Please suggest, which version of 2.4 kernel supports "acpi" and 
where to get that ? 
	It will be better if someone can suggest how to install or upgrade
to new kernel. I mean the procedures and commands. Is there any "url" 
which can give me these informations ? 

	Cheers
