I won't get away, I just stoped trying to "negotiate softly" with
Herbert in order to change anything on the kernel-image packages. Does
not make much sence.

Could you please proof-read the appended diff file?

+If you have no AT-style keyboard and only a USB model, you will need to enable

+installation system. If you enabled this option and it is working for you, you
+are fine and can go ahead. If cannot find this option, this could either mean
+that it is allways enabled and you can continue. It could also mean, the BIOS
+does not provide any emulation support, or you find the option, enable it, but
+the emulation stops working soon after the kernel started. Then you have bad
+luck and should continue reading next paragraphs.
+ <p>
+Sometimes, the emulation hangs but it wakes up after few minutes, so you could

+Using floppy disks rather than boot CD may lead to another problem. The USB

+prompt, try attaching a regular (AT) keyboard in order to enter <Return>. Then
