Basically, the way thing stand now is that merging the pmap fix from
i386 fixes the fault-on-nofault-entry panics, but there remains a
memory corruption problem.
Most times the corruption its a mysterious failure of install when
building libc, sometimes its a segv of make. Silby claims to have
seen this (install failure) on x86, so at least its not alpha specific.
