Bug Description
Here I am cross-posting a comment I made on Artyom's blog. Atar responded that he "fixed these issues for some customers". I hoped that opening a bug to the opensource project might help develop the solution for the public domain.
I now have a mostly-working Solaris 6 emulation, with great thanks to the valuable information in Artyom's blog, brezular.com, and the QEMU/Solaris 4.14 wikibook.

I continue to have a problem, which I have found others posted in blog comments, but have not seen a resolution yet.

Yes, this is a known issue which I can reproduce using a Solaris installation. I still have a few outstanding bugs on my list to do before I can start looking into this one, but I will keep this bug up to date as/when I can start work on it - apologies for not being able to be more specific than this at the moment.
