No difference. With gplpv, the domu network hung just downloading the latest 
flash installer. I had to login to the vnc console to regain control. (I was 
using rdp.) With /nogplpv, it's still mondo slow. (not that I would expect 
changing the above settings would affect that.)

I'm not expecting any quick fix. 2.6.32 works quite well for me. I just wanted 
to give you a heads up on possible problems with 3.0.0 (the kernel :) )
