lssbus is a small utility for Linux/SPARC that probes the sbus and list devices in a manner similar to lspci. Homepage: http://people.redhat.com/tcallawa/lssbus
Created attachment 98884 [details] lssbus-0.1.ebuild
The ebuild needed some touchups (dodoc missing, dosbin rather that dobin) but it's the thought that counts. InCVS, thanks!
