Sorry for the late reply, I was just going through old unread email.
The lpc32xx platform is getting converted to device tree based probing,
which means your board will have to use a device tree file rather than
a board number anyway, which at least solves the problem of getting back
the assigned board number entry.

Please have a look at the phy3250 support in arch/arm/boot/dts/phy3250.dts
and at the files in Documentation/devicetree.
There are still a few bits missing device tree bindings, in particular the
display and the DMA engine, but you can start with a device tree file
that describes everything else.
