Back in July we added the ability to drop local dnsmasq config
into /etc/NetworkManager/dnsmasq.d which is part of NM 0.9.6, released
in early August.  I believe this fixes your problem.

The reason we cannot use the normal dnsmasq configuration is that by
default, that gets read, but there's a *lot* of stuff that uses dnsmasq
these days (libvirt, manual installs, NM, etc) and NM's use of dnsmasq
is quite different from these others, and thus the configuration
directives in the default config file simply don't apply to how NM uses
dnsmasq.

I think your best bet is to either:

1) get Ubuntu to backport the patch (git commit
ac152ece0206b4cde28acf78abb21518e67513e1) to 12.04

2) replace dnsmasq with a shellscript that checks the arguments it's
being called with, munges the arguments, and then calls the real dnsmasq
