As per comment #74, a value of 0x00fdffff also works on a ThinkPad T42. But as explained by Henrique in comment #106, this is a workaround that makes notification go through software key handling rather than hardware events. Following on this, the proper fix will be in kernel 2.6.33 as per Henrique's comments #112, #125 and following.
What this means is that if you update the hotkey_mask as per comments #106 or #133, you will need to revert it to the value in hotkey_recommended_mask once the proper fix is in (either in Lucid or backported from Lucid to Karmic).
