This patch adds locking to wds(4) and marks it MPSAFE.  It also includes 
several other cleanups such as using bus_space instead of inb/outb.  The patch 
is against HEAD but probably applies to 9 and 10 as well.

http://people.freebsd.org/~jhb/patches/wds_locking.patch

Note that this driver is using a deprecated API that will be removed in 11.  
If no one tests updates to this driver then it is not feasible to continue 
maintaining it in the tree.  In that case, it will be removed from HEAD one 
month from today.
