Are you sure? ;-) 

Well in fact this is not lvm2  problem, but problem with incompatible
changes in sysfs design.
(Recent lvm2 userspace code will recognise devices in all cases.)

But maybe there can be other problems, not related to lvm2 with these
deprecated options set - see e.g. http://lkml.org/lkml/2009/3/24/628

So for new kernel with old userspace (like udev etc) enable it, for new
distro with recent userspace keep it disabled.
