And a couple of further references from the 1990s which might be of interest:

Unfortunately not, although we have been working from feminist pedagogy pespective and qeer perspective on a series of workshops with teachers in Sonora, Mexico
I am not sure if his work would fit with your particular interests, but I suggest that you look at some of the work sj Miller is doing. Topics include sexual identities, transgender, bullying, etc.
A colleague of mine at Universidade Federal da Fronteira Sul, Brasil, carries out reasearch on sexual diversity on didactic books and she also works with teacher trainning, Her name is Neide Cardoso de Moura. You can watch her curriculum and get in touch just tiping her name at http://buscatextual.cnpq.br/buscatextual/busca.do

Abstract
This research describes the impact of an integrated training program (Positive Space I and Positive Space II) on pre-service teachers’ understandings of and abilities to create safe spaces for lesbian, gay, bi-sexual, transgendered, two-spirited, queering and/or questioning (LGBTQ) youth and allies in schools. Our Bachelor of Education program incorporates these workshops as part of sociology of education and inclusion classes that are mandatory courses for all pre-service teachers. Our findings suggest that for the pre-service teachers we teach, the Positive Space program is needed if they are to be allies and to interrupt heteronormativity.
