Do we have a portmaster that is not AWOL? :)

ofwboot.xcf and ofwboot.elf are essentially the same code.  We first
build an ELF file (but NB: not ofwboot.elf) and then convert it to
XCOFF.  The only difference of the ELF file from normal ofwboot.elf is
that we provide an "indirect" entry point (see Xcoffxtra.c) that XCOFF
requires.  But for my experiments I built ofwboot.elf and ofwboot.xcf
that were identical content-wise (xcoff uses _entry indirection, elf
has _entry indirection but uses _start directly).

The context switch vs. FPU issue has been fixed a while ago.  It's
been pulled up to -6:

chs@ fixed the mutex issue in late February.  It's been pulled up to
-7 but not -6, I think.  See

  http://gnats.netbsd.org/44387

So you might want to try to apply that change to -6 and see if that
helps stability.
