I forgot to mention I have a 5660 17 months old, though still running strong. Since Sager will\won't update drivers for their older models. I just go to the various manufactures sites to get the drivers, Smlink (modem), Realtek (audio, networkcard), Synaptics (touchpad), ATI (video). Have not had any issues using the drivers from these sites. I have to use DHmodtool 1.7 to mod the inf files for the ATI vid drivers, other than that eveything installs with out issue.
PS: IMHO Realtek is the king as far as supporting their drivers
