I've not seen a picture of Brisbane yet. It is supposed to
be much more like an optical shrink. It's hard to make estimates.

Keep in mind that some parts like the integrated "Northbridge"
functions do not scale at all, for instance the DDR interface
which is 31 mm2 by itself alone on both the 90 nm Rev.F
processors and the 65 nm Barcelona.

Say that, for example, 40 mm2 is non scaling Northbridge I/O
area, then:

(183-40) * (65/90)^2 + 40 = 115 mm2

Is what the die should be in the case of ideal scaling.
