Aligning data is the driver's responsibility.

The kernel should not fail though even when it is misaligned, only be slow
because of misalignment traps. This is needed because the driver can not 
always predict for all cases (e.g. EthernetII and 802.3 require different
alignment to get aligned TCP/IP), so it should optimize for the common
case. 

(if that is not true on mips then it is a mips bug)
