I have tried Linpus Linux Lite 9.4 and had exactly the same problems you are describing (tried it on radeon 9200, nvidia 6200 and nvidia 7800 ... all the same failure.
What I did to overcome this was to change terminal by pressing Ctrl+Alt+F8 (you can try F9 as well), then I changed to the /etc/X11 directory and overwrote the existing xorg.conf with the vesa xorg.conf. This enables the system to start graphically.
The exact copy commands after logging in as root were:
cp xorg.conf.vesa xorg.conf (Y to overwrite)
This loads the Linpus desktop in Vesa mode so you can have a look at it.
I am now currently working on being able to install this OS onto a HDD so that I can repair it and have it work correctly, then I will look into remastering it into another ISO so that it loads the vesa driver by default.
Hope this helps
