For the person who asked about "ia32 to ia64" crosstools....At least for the OpenSUSE 10.x hosts all kind of crosstools seem to be available in those
OpenSUSE package archives like the Finnish one for OpenSuSE 10.0 :ftp://ftp.mirrorjames.com/opensuse/distribution/SL-10.0-OSS/inst-source/suse/i586
Similar things also for the 10.1 in its own directory...
