Such notebooks are clones of Fujitsu Amilo V2000, the hook for the v2000 is being used and I have tested that perfectly works. The immediate result of integrating this patch is that the five special buttons will work on these specific notebook models and that the RF killswitch will not be activated after suspend. This patch definitively obsoletes the fsam7400 module which I was still needing to enable wifi and to fix the RF killswitch suspend problem; in the current 2.6.30 kernel it is necessary to load the wistron_btns module with options 'force=1 keymap=1557/MS2141', which was not anyway a complete workaround.
