For the pork and stock: Cook the pork butt with 2 cups of the julienned onions, 5 cloves of the garlic and 5 cups water until the pork is cooked through, about 45 minutes.
Meanwhile, in a pot, combine the tomatillos and jalapenos and cover with water. Simmer for 20 minutes. Drain, reserving the tomatillos, jalapenos and 1 cup of the cooking liquid.
Saute the remaining 2 cups onions and 3 cloves garlic in some of the canola oil until golden brown. Transfer to a blender and add the cumin and reserved tomatillos, jalapenos and 1 cup cooking liquid and blend until smooth. Put the remaining canola oil in a pot and heat until smoking. Add the tomatillo mixture to the pot and cook for 5 minutes. Add the chicken stock and cook for another 15 minutes.
When the pork is cooked, season with salt. Pull out the pork and discard all that remains. Add the pork and hominy to the pot with the tomatillo broth and cook for an additional 10 minutes. Adjust the seasoning with salt and pepper.
For serving: Ladle the soup into bowls and top with some cabbage, white onions, Mexican cheese, cilantro and fried tortilla.
When blending hot liquid, first let it cool for five minutes or so, then transfer it to a blender, filling only halfway. Put the lid on, leaving one corner open. Cover the lid with a kitchen towel to catch splatters, and pulse until smooth.
