Neither gets to an OpenBIOS prompt afaik. Nor to the Welcome banner of  
the Haiku bootloader, so iiuc not to its payload either.

Complete previous output from the mail I replied to:

checking for memory...
0: base = 0x00000000, size = 134217728
1: empty region
total physical memory = 128 MB
suggested page table size = 1048576
need new page table, size = 1048576!
new table at: 0x07d00000
MSR: 0x00003030
found 4 translations
found page table!
no mapping for the exception handlers!

Similar report on qemu-devel:

The output I sent was supposed to be complete (minus the OpenBIOS  
banner we all know):

checking for memory...
0: base = 0x00000000, size = 134217728
1: empty region
total physical memory = 128 MB
suggested page table size = 1048576
need new page table, size = 1048576!
new table at: 0x07f00000

Partial output from real hardware for comparison available here:

I considered it a regression because it's four lines less of output.
There's also a change of address for the new table - 0x07f00000 vs.  
0x07d00000.

Looking into that.
