Pierre, No you shouldn't come to that conclusion. Welcome to the wonderful world of kernel mode video drivers. :) In lucid, kernel mode video drivers can load and perform "modesetting", meaning setting the video mode from the kernel (whereas modesetting to-date had been a function of the Xserver).
You can try adding a kernel parameter to tell the kernel NOT to do modestting by adding the following to the kernel command line in /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default: nomodeset While this may fix the issue for you, keep in mind that the video developers are really trying to move to kernel modesetting and away from having the Xserver video drivers perform modesetting (so you might see a performance hit).
