[Samba] Won't %L work anymore?

A followup to my own post:

I went ahead and implemented a configuration with %L.  It works great.
One problem: Micro@!#$t broke Win2k with SP3.

My test PC was running Win2k SP2.  When it connected to the server it
seems to have supplied the "netbios name" of my server.  I went into
my boss's office to show him how great this works and his Win2k SP3
did not show the same shares.  They showed the shares that would
show if the "real" host name is used.

Here's my basic config:

System OS: Solaris 2.6
Samba: 2.2.7
Hostname: tea
IP addresses assigned: (tea) (cup) (mug)
Partial configs:
             interfaces =
             include = /etc/samba/smb.conf.host-%L
             workgroup = MTLAUREL
             netbios name = TEA
             workgroup = MTLAUREL
             netbios name = Cup
             workgroup = MTLAUREL
             netbios name = Cup

So, am I crazy to think of using %L?  Should I use another (hidden) % code?
Should I hack in %s (for sockname) or %l (for alternate %L) as the result
of getsockname()?  Will this even work?  Is this any different in samba 3?
