:-) I think there is more to it, for example we should avoid 
re-allocating a page which has a hard error to make sure that the next
user stumbles over this again. Maybe this information should also be
kept accross a reboot for the same reason. Then you need some API to maintain
this information, if for example a DIMM is replaced and it is not longer
require to map out a page with an error.
