LGTM, although I'll yet try to verify it with hardware.  But it'll have 
to wait another week or so as I'm currently away from my lab and this 
requires physical presence.
NB I suggest that you request your change to be backported, i.e. post v3 
with:
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
Cc: stable@vger.kernel.org # v2.6.12+
