You may be on to something here:

[root at sheeva ~]# uname -a
Linux sheeva 2.6.36.2-vs2.3.0.36.38.2-kw #1 Wed Jan 5 17:54:59 GMT 2011 
armv5tel armv5tel armv5tel GNU/Linux

[root at sheeva ~]# cat /proc/cpu/alignment
User:           12230853
System:         1
Skipped:        0
Half:           0
Word:           0
DWord:          1
Multi:          0
User faults:    0 (ignored)

What does that imply, then?
