have been added as OSIDs so that the parser accepts them. os_setup
maps them into whatever equiv OSID is loaded on the target node,
according to the OS slot of the osid table entry. If no mapping can be
made (no equiv OS loaded, as defined by the partitions table) os_setup
fails. I've also changed the web page node control form so that the
only OSIDs you can set for a node are the ones loaded (partitions
table) or OSKit kernels (osid table entry has a path).
