My problem is that at HEAD *none* of the i386,ppc,sparc guests that  
used to work about a month ago boot *at all* on my Darwin/ppc64 host.

Might be TCG, might be the new MemoryRegion API, might be (non-)I/O  
thread. Means a lot of git history testing despite little time. An  
ultimatum to make things even worse doesn't really help there... ;)
