Third Party Software Support for Linux on SGIs?

Dan Christian asks: "I just got off the phone with SGI support. They tell me that they are no longer offering software support packs for their Linux boxes and my initial 90day support has run out. Where can I find good free information or third party support for my SGI 300L? This is really annoying, since the box is only 4 months old and there was no notice that it was becoming un-supported."
