Solve for A,B,C,D,E,F as unique digits 09: ABCDE x F = EDCBA

In Y x k = Z,
k is a single digit from 29, and
Z has the same digits as Y in reverse
order (i.e. if Y = 241456, then Z = 654142.)
Find all combinations (Y,k) that
solve the equation.
It may seem like the second problem is much too undefined.
Actually, the solutions can be reduced to some simple descriptions.

Original, though I wouldn't be surprised to find these printed
somewhere else.
