That's certainly unexpected. The n900 has (iirc) a Cortex-A8, which as an ARMv7 core, can perform unaligned accesses to normal, cacheable memory in hardware.
Can you provide your .config and/or any information about your network chip please? There's a chance that the driver is doing something odd.
Cheers,
Will
