Okay, I got passed the issue with formatting the root filesystem.
Apparently there are some limitations on the C/H/S parameters you use
for the disk that correspond with how UFS wants to format a new
filesystem. I'm not sure what exactly those limitations are at this
point, but, by adjusting a couple of the C/H/S settings when using
format to set up the disk I was able to get it to work correctly. So, I
now have Solaris 9 installed on qemu-system-sparc with OpenBIOS! I'll
probably go back to Solaris 8 as that one has a free binary license
while Solaris 9 is a commercial license, IIRC. I do own a Solaris 9
commercial license, but I like the free idea, better.
Anyway, now I'm on to an issue with networking - I've used the following
two qemu network parameter combinations:
-net nic -net tap,ifname=tap0
-net nic -net user
In the first instance, tap0 was configured on my Linux box and added to
my bridge br0. In both cases the Solaris system is unable to obtain a
DHCP address - the DHCP client times out. Not sure if I should be using
a different parameter set, or if this is another area that needs some
work either for OpenBIOS or qemu?

I'm trying to get the sparc32 OpenBIOS to load an fcode rom, but it's
not working. After byte-load, it reports out of memory.
Here's the steps I'm using to setup a simple rom which just sets the
device name to "QEMU,test", and then trying to run it:
fd000000 1000 l!
00000020 1004 l!
12095145 1008 l!
4d552c74 100c l!
65737401 1010 l!
1412046e 1014 l!
616d6501 1018 l!
10000000 101c l!
cd /iommu/sbus
" /iommu/sbus" select-dev
new-device
1000 1 byte-load
Here, OpenBIOS will report out of memory.

ppc: add POWER4 cpu description
So far, we only supported the 970fx CPU type inside guests. Unfortunately, that
CPU supports Altivec. Not all KVM capable host CPUs do have altivec though, so
they're left out in the rain when running openbios in the guest.
This patch adds POWER4 CPU description, allowing users to specify at least one
CPU type that does not require Altivec, but is still 64-bit capable.

ppc: only clear MSR_SF when clearing high MSR bits
We are pretty aggressive now with how we clear the high MSR bits, clearing
all of them when we find a 64-bit CPU.
As Segher points out, this is not always a good idea though. There might
be bits set that can be crucial for operation. Hence we should only clear
MSR_SF, as that's the bit we're interested in.
