Hello,

As explained on the mailing list and on irc, this is not a proper fix,
since it will result in a two time error message when airport card is
not present or when the subarch doesn't support airport cards.

A proper fix would do the following : 

  1) test that we are on newworld pmac. No oldworld or non pmac
  subarches will have airport cards.

  2) if we are on newworld pmac, check /proc/device-tree for a mac-io
  mode, and if this node contains a child named radio, then we have an
  airport card. I believe that this node even has more info that what we
  need. I suppose that for 2.6 kernels we could even use /sys for that,
  but we will need to check the exact paths used, and my ibook doesn't
  run 2.6 right now.

Algorithm proposal : 

  db_get debian-installer/kernel/subarchitecture
  SUBARCH="$RET"

  if [ $SUBARCH = powermac_newworld ]; then
  	if [ -e /proc/device-tree/aliases/mac-io ]; then
		if [ -e /proc/device-tree/`cat /proc/device-tree/aliases/mac-io`/radio ]; then
			/* do magic airport loading */
		fi
	fi
  fi

Unless there is opposition about this, i will implement this during this
WE at the Munich BSP.

Friendly,
