I understand and sympathize with the motivation behind this - I really do. Just... I wouldn't get your hopes up.
For the past efforts: By 2003 SGI was committed to Altix/Prism/VW xx 0, and Windows or Linux, as the core product set. Ignoring Windows, I can understand how it would make sense to extract things that were unencumbered and could be useful to differentiate these platforms/systems. And part of the marketing around Linux was participating broadly in FOSS, so opening up the parts you were working on actively made some sense. XFS is a great example because that gave them a useful differentiator and selling point, but they weren't cutting their own throats by exposing most of it, since their competitors already had alternatives. As for 4Dwm and other workstation bits, they were committed to Windows on the one hand, and I guess they decided they didn't want to deal with having to support it on Linux on the other, so it didn't happen.
These days Rackable/SGI does nothing with IRIX, and they're not about to start doing anything with IRIX again. The question at this point is, what motivation do they have to reassign busy engineers and pay them to go back, relearn the code base, separate out the interesting and unencumbered bits that they didn't already pull out in previous efforts, package each component or subsystem up, explain to the lawyers why they should give it away for free, convince more lawyers they won't get sued by somebody looking to make a quick buck, and then actually release the stuff?
I'm not saying don't do it - heck, I signed one or two petitions around this in the past. Just don't be too shocked if the response from Rackable/SGI is ... underwhelming.
