Instructions on setting up X-Amiga on qemu are now on the website.
Look for the FAQ page (it doesn't appear on the home page yet! Just go to any other page, you'll see the link at the bottom...)
I don't have vmware, so can't really help much. As for this infuriating GRUB issue - there's a fix for that on the website too, just hope it works for everyone.
