Oh you can easily fix that by adding a n900 specific
DT_MACHINE_START entry to mach-omap2/board-generic.c.

The revision entry you can populate too in pdata-quirks.c,
or maybe add something generic to populate it based on the
cmdline or a dts entry as I believe that comes from the
legacy ATAGs. I think that's just the system_rev or some
other *_rev global in the kernel.
