Well, of course. If the driver doesn't believe your monitor / card
combination is capable of that mode, xrandr won't be able to set it.
That's normal. You need to set up xorg.conf so that the mode is
available.

What monitor *is* this, anyway?

They are likely using older X server, kernel and intel driver, so
they're not very comparable. Ubuntu's results seem nuts - it claims
2048x1536 as a 'probed' mode. Very few monitors are capable of that.
