Aparently fixed with latest HEAD *kernel* :

# svn log -v -r224842
------------------------------------------------------------------------
r224842 | rwatson | 2011-08-13 18:03:40 +0200 (sam 13 ao=FB 2011) | 10 lign=
es
Chemins modifi=E9s=A0:
   M /head/sys/kern/vfs_syscalls.c

When falloc() was broken into separate falloc_noinstall() and finstall(),
a bug was introduced in kern_openat() such that the error from the vnode
open operation was overwritten before it was passed as an argument to
dupfdopen().  This broke operations on /dev/{stdin,stdout,stderr}.  Fix
by preserving the original error number across finstall() so that it is
still available.

Approved by:    re (kib)
Reported by:    cognet

------------------------------------------------------------------------

You won't be able to buildworld with the buggy kernel, but you can
buildkernel and reboot on the new kernel. No problems with portsnap
after that (don't know if you have to clean the old portsnap files, I
did it).
