I think that one needs to worry about write-caching controllers only for hard disks, but I may be wrong. About the light staying on for Linux/Solaris. I consider this to be a bug since the user should get an indication that the device is no longer in use. I will google^Wcheck whether there is some discussion on this in the various mailing lists.
