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.
Yep, Cortex-A8 and it has no problem to do unaligned memory accesses AFAIK. I suspect it is a driver issue, not CPU.
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.
The chip is TI wl1251, you can find the config file here(actually this is the tree I am using to boot 3.14-rc1 on N900) - https://gitorious.org/linux-n900/freemangordons-linux-n900/source/1434dbd7fbc5ec257b6cd6c547689b79177d1937:arch/arm/configs/rx51_defconfig
