Same with N420D / GeForce 2 integrated
BTW it's the same problem with the N420D-chipset based board hosting a GeForce 2 integrated GPU.
I have boot up times for X-Servers of about 1 minute.
Screen gets black, nothing happens, looks like hangup, after half a minute wild flashing of the screen, a little later "CHR-salad" on the screen (definitely a sure sign of something going wrong). Just after that the NVidia-Logo. And X starting.
