Sorry to be the barer of bad news, but I discovered the following:

1) The current tar_files directory is missing in NetBSD-current:

	ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-current/tar_files/

   so, I can't find "sys.tar.gz".  Prehaps this was accidently
   overlooked when the FTP server was replaced after the old one
   died?

2) NetBSD-current won't build with unmodified GENERIC (i386).  It
   fails, when it tries to compile "linux_sysctl.c".

Does anyone have a recent kernel tarball (sys.tar.gz) that can
build with GENERIC (i386)?  I urgently need a recent kernel to
use with a Atheros AR5212 mini-pci Wi/Fi card I installed in my
laptop to replace to useless Intel Centrino Wi/Fi.
