Hmmm.
- From your /proc/bus/usb/devices I would expect this to read 'usbhid'.

These last two lines mean that no keyboard was detected, so you should 
have been presented with the option 'No keyboard to configure'.

Well, actually there were two problems here.
- - I should have set present to UNKNOWN instead of FALSE; this is closest
  to the old situation for other architectures (minor error from me).
- - The existing code that adds a 'no keyboard to configure' option to the
  list was broken and would never be added.
  I fixed this, but this will lead to that option to be added in a lot of
  installations with 2.4 kernels (visible only at medium/low priority).

Thanks for including that.

I've also added the functions to avoid double entries in the arch 
selection dialog (as discussed with joeyh yesterday on #d-boot).

I've committed the changes to svn after testing as far as I can, so please 
test this new version again.

I'd also appreciate a review of my changes for C syntax.

(bubulle: I did _not_ upload a new mini.iso; please build one yourself)

Cheers,
FJP
