One problem with the patch is that, since I don't have a page 7 (bay 
names) it's using the "enclosure component index" as the name, and that 
(at least for me) seems to be an index starting from zero, where my bays 
are numbered from one.

sg_ses shows a "bay number", I think I'll try to make the patch look for 
the bay number and make the name something like "bay-nn" if there is a 
bay number.
