FWIW here is my fastest solution:
from itertools import chain
def compute():
str_=str; int_=int; slice_=slice(None, None, -1)
for x in chain(xrange(1, 1000001, 10), xrange(2, 1000001, 10),
xrange(3, 1000001, 10), xrange(4, 1000001, 10), xrange(5, 1000001, 10),
xrange(6, 1000001, 10), xrange(7, 1000001, 10), xrange(8, 1000001, 10),
xrange(9, 1000001, 10)):
rev = int_(str_(x)[slice_])
if rev>=x: continue
if not x % rev:
print x,
compute()
