Another big difference is that the default loss function in Linear SVC is
quadractic with distance to the margin (loss='l2') while it is linear in
SVC.

Actually for the chi2 kernel 2xy/(x+y) you can do a prolongation by
continuity at 0:
lim_(x->0) chi2(x,0) = 0
And you should also do it for the feature map so phi(0) = 0.
so a simple test for (x==0) will keep the feature map
correct and keep the sparsity
