I've updated the patch  
(http://www.Leidinger.net/FreeBSD/linuxolator/linuxulator_mfc.diff).  
It may still not build on amd64 as I changed a lot, but the problems  
you pointed out should be fixed. It builds on i386, but I don't know  
if it works.

Here's the current state of affairs:
---snip---
  - kern_descrip.c rev 1.296, syscallsubr.h rev 1.41 by jhb:
    Add a kern_close() so that the ABIs can close a file descriptor w/o having
    to populate a close_args struct and change some of the places that do.
  - sync linuxulator (bugfixes + minor syscalls):
    * mmap fixes
    * fix memleaks
    * add syscalls:
      + stat            (i386, amd64)
      + iopl            (i386, amd64)
      + mprotect        (i386)
      + rt_sigpending   (i386)
      + rt_sigtimedwait (i386)
      + statfs64        (i386, amd64)
      + utimes          (i386, amd64)
      + timer_*         (i386)
      + mq_*            (i386, amd64)
      + settimeofday    (amd64)
    * more errno value mapping
    * don't limit number of syscalls to 255
    * ioctl TIOCGPTN
    * handle more socket options
    * de-COMPAT_43-ify:
      + sethostname
      + lstat
      + ftruncate
      + nanosleep (i386)
      + socket related ioctl's
    * add more dummy syscalls so that we know what is needed
    * handle address space limit
    * style(9)
  - sync linprocfs
    * /proc/sys/... part

I think this is something Roman (CCed) could investigate... :)

Bye,
