once the programs have been installed, it is safe to remove the tarballs 
and unpacked source code.

make sure that you have mtrr support turned on in your kernel 
configuration (under the 'processor type and features' category if you 
use 'make menuconfig'), and enable advanced power management bios 
support under the general setup category.  there are several options to 
select in your kernel configuration under the power management 
selection; what works for me is to 'enable PM at boot time' and 'Use 
real mode APM BIOS call to power off'.  you may have to experiment with 
different combinations of the options there, i think this feature is 
somewhat processor dependent and the options i mention above may not 
work universally for every processor/motherboard configuration.
