Why do you keep believing that dual-boot XOs will actually ship?

Windows XP is **using** the NAND storage.

There is no support for partitioning it. Even if both Linux and
OpenFirmware were to support such a thing, you'd have to get
Microsoft to agree to something that makes no business sense
at all.

Supposing you managed to get that miracle, you'd have to
convince countries to ship a system with two OSes that are
both about to run out of space. Microsoft will of course be
pushing for a better Windows experience, meaning all space
is allocated to Windows. (but this is theoretical, because you'd
need a miracle to get partitioned NAND support into Windows)

BTW, if NAND size were doubled, that would mean more NAND
available to Windows. If there were so much NAND available
that Windows had no use for it, Microsoft would find a way to
purposely waste the additional NAND.

I can't imagine why. LinuxBIOS (now coreboot) didn't.
Even EFI didn't. Your wishes are not their wishes.
