My /etc/modprobe.conf already had:

alias eth0 8139too
alias snd-card-0 snd-ens1371
options snd-card-0 index=0
options snd-ens1371 index=0
remove snd-ens1371 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; 
/sbin/modprobe -r --ignore-remove snd-ens1371
#
# Ta prosthesa ego
# I2C module options
alias char-major-89 i2c-dev
# nvidia kernel module
alias char-major-195 nvidia-169_12
alias nvidia nvidia-169_12


So the new line is:

options nvidia-169_12 NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1 
NVreg_ReqAGPRate=4


What are the variables "NVreg_EnableAGPSBA" and "NVreg_EnableAGPFW"?
