wvdial make freeze dist-upgrade from breezy to dapper by net

booting on K7 kernel last updated under breezy 5.10
launching "sudo apt-get update && apt-get dist-upgrade -y"
every things attempted will go
but
when trying to download and install "wvdial", freeze (more than hours)

Need to boot on i386 kernel
Need to "rm" wvdial data every where
Need to make a "dpgk --reconfigure -a"
Need to restart "sudo apt-get update && apt-get dist-upgrade -y"

but I have an answer like : "nothing new, nothing to install"
 then reboot on new K7 kernel on dapper

then Xserver can't launch because no glx found for the graphic card (an nvidia Geforce 6200)

then make a "apt-get install nvidia-glx"
that's run and uninstall nvidia-settings

reboot

loading K7 kernel on dapper

and that's good.
