Both of those sites load perfectly in Safari for me. OS X 10.3.3 and Safari 1.2.1. Sounds like either you've got an older version of Safari or something's gone wrong - corrupt Safari installation or possibly a plugin making a mess of something.
They work perfectly well for me too with the same config.
