I'm not the official maintainer, but I've done some work on this and so 
can probably answer your question.

Sadly sun4u support isn't quite there yet; it's enough to boot Linux 
(and with git master you can actually start booting the *BSD kernels and 
Solaris) but there are still some issues with the device tree that need 
to be resolved in order for this to work.

In theory the only remaining issues in order to get a headless (serial) 
Solaris to boot in QEMU are to fix up the PCI BARs/interrupts and then 
to switch the RTC over to MMIO access, but I ran out of time to do any 
more development work this release cycle.

As my QEMU work is unsponsored, I'm afraid the pace of development is 
restricted to what I can do in my spare time. If you're not subscribed 
to the list full time, I can let you know when I make any further 
progress if that helps?


ATB,

Mark.
