Olá Roberto, The file T126L28.ctl gives up the clue:

Whatever "ydef 98 levels" means, it looks like there is one Y ordinate for each
one of the 98 rows.
So your upper left and lower right values are in fact -150.0 -61.246 0.9375
29.454.
I create a VRT file based on that:
$ gdal_translate -of VRT T126L28.grb T126L28.vrt -a_ullr -150.0 -61.246 0.9375
29.454
And I opened it on QGIS and the image looks pretty good to me. See attachment.
Since you don't want to convert the data to other format you can create VRTs
and use then instead.
DATA "c:/ms4w/data/raster/T126L28.vrt"
Does it make sense?
PT_BR: Revisando: Eu interpretei o arquivo .ctl, achei a extensao da imagem e
criei arquivos vrt
passando estes parametros. Agora quando eu abro o arquivo vrt os dados
continuam sendo lidos do .grb
mas com a descricao do vrt. Tente fazer o mesmo pra ver se resolve pra voce.
(eu estudei no INPE :)

Ivan
