Yes, we have the v4 release, but, well, it pretty much sucks. I did send a message to a person at Adobe who replied that
Contrary to what people presume, coming out with a huge product like a Reader on an additional platform, isn't simply a re-compile. There are various 3rd party components that the Reader ships with (internal and external) and the team needs to evaluate what the schedule for these dependencies would have, also there's a ton of extra testing involved the moment we add an additional platform. Also, there's market viability, where we look at the numbers or the traction a platform is getting before we take a decision.
It's not clear to me that if they have versions for both Linux/x86 and Solaris/SPARC that creating a version for Solaris/x86 should be all that difficult. I can't think of where they would have library problems. I do understand the testing point. Testing GUI-based programs is a human-intensive undertaking. I don't understand how "market viability" for Solaris/SPARC could be better than Solaris/x86 at this point.
He also included a pointer to the Adobe 8.1.1 FAQ: http://blogs.adobe.com/acroread/2007/09/adobe_reader_811_faqs.html
