We have other systems where 32-bit kernel support is just remarkably ugly. We've dropped 32-bit support for the SGI IP32 aka O2 - nobody seems to even have really noticed that. The Sibyte systems would be good candidates to do the same as accesses to outside the 32-bit address space are needed very frequently. Ralf
