>Description:
	mount_smbfs will not work with smbfs module unless smbfs module
        loads libmchain module.

>How-To-Repeat:
	do the following: compile a -STABLE kernel without LIBMCHAIN
	and without NETSMB options. Include the LIBICONV option 
	(this does not seem to compile as module, ok).

	Now mount_smbfs some filesystem.
	It will fail with error message: 
		smbfs: vfsload(smbfs): Exec format error
	then kldload libmchain
	re-try mount_smbfs command... bingo everything works again.

	As a side note: If I compile options NETSMB, option LIBMCHAIN
	and option LIBICONV statically into the kernel then 
	mount_smbfs will fail with: smbfs: vfsload(smbfs): File exists.

	Seems like the vfsload will try to load the module but if its already
	there statically - it does not detect this fact and gives up.
	I recon some detection code would be in place here. 



>Fix:

	see ideas on how to fix it above.
