Ben, you that know the internals of fbdev's, it would be difficult to implement the busid stuff? Maybe that info is already known by the drivers somewhere... It could even work for sparcs with sbus or others archs with differents buses, as the busid nomenclature is very standarized i think. -solca ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
