Generalization of Raynaud's (p, p, ... p) result Does Corollary 3.4.4 in Raynaud's paper ``Schemas en Groupes de Type (p, ..., p)'' apply also to the case where G is quasi-finite? If not, what is the more general statement? 
The corollary states:
``Soit G un K-schéma en groupes fini, commutatif, annulé par une puissance de p et qui se prolonge en un R-schéma en groupes fini et plat. Soit H un quotient de Jordan-Hôlder de G. Alors H est un schéma en F-vectoriels, pour un corps fini convenable F. Si F à $p^r$ éléments,
le caractère $\psi : I_t \to F^*$, qui décrit l'action du groupe de Galois $Gal(\bar{K}/K)$ sur le F-vectoriel $G_i(K)$ est alors de la forme
$\psi = \psi_{i + 1}^{n_1} \cdots \psi_{i + r}^{n_r}$ avec $0 \leq n_j \leq e$ pour tout j.''
(Here, R is a strictly Henselian discrete valuation ring, K is its fraction field, char K = 0, and p is the residue characteristic of R.)
 A: As James Borger writes in his comments above, the answer is surely no.  The restrictions on the characters appearing in the Galois representation attached to $G$ are being forced by the fact that $G$ has a finite flat model.  If you throw that assumption away, you lose any control on the ramification of the Galois action on $G(\overline{K})$, and it can be whatever you like.  
(The point is that any representation of $Gal(\overline{K}/K)$ on a $p$-power order abelian group, or on an $F$-vector space for some char. $p$ finite field $F$, is the group 
of $\overline{K}$-bar points of a finite group scheme, or $F$-vector space scheme, over $K$.  But if the ramification conditions in the conclusion of Raynaud's theorem aren't met, then this group scheme won't have a finite flat prolongation over $R$.)
If you want to have a theory generalizing Raynaud's theory of finite flat group schemes
which applies to other representations of $Gal(\overline{K}/K)$ (i.e. ones that don't come
from finite flat group schemes over $R$) then you will need to learn integral $p$-adic Hodge theory, which is a highly developed theory.  The first step is to learn something about Fontaine--Lafaille theory (which deals with the case when $e = 1$).   The step after this is to learn about Breuil modules and/or Kisin modules.  But all of this is rather technical and involved, and a serious investement to learn.  So you might be better off explaining your motivation and goals, so that people can give more specific and appropriate advice.
