Hello Rhys and Larry, at all,
 I am writing just to thank for the help. After a dark period I could 
install the hugemem and the problem disappeared. The wa indices in top 
fell to acceptable levels and the machine is having a better performance 
but still well lower running the gentoo livecd. As the problem was 
solved, I had to recover all the work that was delayed, and I have not 
had time to investigate the .config of the two kernels, but I will do 
it. As soon as I finish this, I will inform you of my conclusions.
Thanks again.

Eduardo Bach
