It seems my kernel crashes were due to using gcc-4.8.2 to compile ski,
going back to gcc-4.7.3 for ski, and gcc-4.3.6 for cross-compiling
the kernel, gives me a solid emulated system.

The ski project on sourceforge seems dead, nothing have been posted
on its mailing list since 2008, and the web interface for browsing
the source repo is broken.  Red Hat, Gentoo, and Debian package ski
with a few common build fixes, but that's it.
