The majority of the patches are hardware specific which puts them in
a lower risk category.  There are two which remove drivers, one which
removes a power PC console (which is likely not an issue) and one which
marks several serial devices as BROKEN.  Not knowing the nature of the
issues ie. how broken they are it may be expedient to leave them as they
are for Karmic.  There are some good looking KVM fixes and some futex
fixes which look to sort out userspace hangs.  There are also a bunch of
ports architecture fixes which look useful.

Overall I think we should accept this pile probabally without the two
driver removals.  More detailed comments at the bottom of this email.
