I could *definitely* build another version of X and start it after boot,
but the problem I've had is that, at least on the Mac, I can't get QEMU
to build w/ libSDL, and the Cocoa UI doesn't work when you use OBP.  See
bug #1260555 and https://trac.macports.org/ticket/41435 ...

That is AWESOME news.  Really, I'm hoping to just have a text-based
console like on my SS5 with the old familiar Sun logo and to start

Again, great news.  I'm running Solaris 2.5.1 ... any clue if OpenBIOS
might work for me?

If I may, do you know why qemu-system-sparc w/ OBP ignores the following
prom-env options?

   -prom-env 'boot-device=disk1' -prom-env 'auto-boot?=true'

Title:
  qemu-system-sparc  in qemu 1.7.0 fails to boot with Sun ROM

Status in QEMU:
  New

Bug description:
  
  1.7.0 seems to have broken booting on SPARC ... at least with a Sun ROM.  
Everything fails with "data access exception."  1.6.{1,2} qemu-system-sparc 
binaries both boot the same images that 1.7.0 fails to boot.

  Type  help  for more information
  ok boot disk1
  Boot device: 
/iommu/sbus/address@hidden,8400000/address@hidden,8800000/address@hidden,0  
File and args: 
  Data Access Exception

  Starting with following command:

  sudo qemu-system-sparc -m 256 -M SS-5 -nographic -bios
