I don't continue instalation Gentoo on Sun Blade 100, becouse after command # emerge genkernel appear this command !!! Couldn't download genkernel-3.0.1_beta12.tar.bz2. Aborting.
Can you try to sync and use a newer genkernel? I'm closing as solved since that beta's source was pointing to brad's personal webspace space rather than a mirror, and when he was gone it got broken. It's fixed in newer portage snapshots / cvs. Thanks.
