36Mhz should be fine..
I ordered a couple of those, in 36, 40 and 50 MHz, let's see how far I get ;)

The CPU maxes out somewhere around 38-40MHz. Difficult to exactly tell as my scope has trouble locking onto the frequency.

I have been looking at oscillators and the 5 V ones do seem to be incredibly hard to find. Not only that they are just physically too big to mount them anywhere on the board.

So I have been looking at 3.3 V ones, smaller SMT types which I take up a few millimetres of space. Because only day 3.3 V regulator as well, but these are often tiny anyway. So I should be able to squash both of these on the board without having to make the board physically larger.
