The wear-levelling on the N900's NAND is handled by the JFFS2 filesystem AFAIK.

Mind elaborating more on that?

Actually, on the N900, its Ubifs, not Jffs2. All bad blocks and such are handled by the OS at the filesystem level, as opposed to being done in hardware on a SD card.

However, the 2mb Kernel partition does -not- have any real filesystem, and thus, no wear-leveling.

So that means in the end the way Multiboot handles the kernel image doesn't wear-level anything in the n900?

No, but you'll have to erase/write it something on the order of 10000+ times (on average) to kill it.
