Okay, it's solved: adding "vga=normal" to the kernel parameters does the trick.
Please apologize that I didn't find this solution (out of Ubuntu documentation) earlier. Nevertheless, this could be a problem for other persons. Perhaps this kernel parameter could be added automagically if a ATI card is detected?
