Thanks, I've uploaded one of them to Intrepid yesterday.  (Sorry for the
delay - there were several xserver patches needing to be straightened
out first.)

I've reviewed this and discussed it with Timo and we think it's safe to
upload to Intrepid, which I'll do today.

I suspect it is also safe for doing a SRU for, however I would want to
see it thoroughly tested first.  Let's have it in Intrepid for a week or
two before putting into hardy-proposed.  We need to verify both that 
a) it fixes the PS3 issue, and b) doesn't cause weird behaviors for
anyone else.

Looks good, and I think it should be fine to SRU directly.  I'll also
push this through into both Intrepid and hardy-proposed today.

This is the one I uploaded to Intrepid last night.  Please validate when
you get a chance and let me know if we should go ahead with the SRU, and
then I'll upload it to hardy-proposed.

Would you like to do the legwork on the SRU's for these three?  It's
pretty straightforward, but I can give you guidance.  The directions are
at http://wiki.ubuntu.com/StableReleaseUpdates; I will take care of
steps #1 and #4 of the procedure, but it would be very helpful if you
could do esp. step #3 (which you've mostly done already).
