Thats as far as I've got.  There are more complete dumps at:
  http://people.freebsd.org/~peter/hammer.txt

Note this is a modified i386 loader that understands both 32 and 64 bit
kernels.  In the link above, you can see the same loader on both types.

It's still rather green, I've only been (seriously) working on it since
friday.  Jake's PAE commit showed me a way that I could defer dealing too
much with pmap yet.  In the logs above, it corrupts itself and crashes
while trying to prepare to exec /sbin/init.  I'm pretty sure I have
hosed the copyin/out stuff and/or the [fs]uword*() functions.

If you are interested, you can see what is going on here:
  http://perforce.freebsd.org/chb.cgi?FSPC=//depot/projects/hammer/...
  http://perforce.freebsd.org/dtb.cgi?FSPC=depot/projects/hammer
(yes, the trailing /... is important)

Cheers,
