Well, if you want to have some fun with list comprehensions . . . :

 >>> v = "64x43x12"
 >>> [i[::-1] for i in v[::-1].split("x",1)[::-1]]
['64x43', '12']

On the other hand, if you're not as list comprehension happy as I am, 
you could write a function to do the same thing:

 >>> def rsplit(string, sep=" ", maxsplit=-1):
       string = string[::-1]
       stringlist = string.split(sep, maxsplit)
       stringlist = stringlist[::-1]
       for i in range(len(stringlist)):
             stringlist[i] = stringlist[i][::-1]
       return stringlist
 >>> rsplit(v, "x", 1)
['64x43', '12']
