No, Chris, surely not. I read it as meaning what it says:
"Please upgrade your kernel before or while upgrading udev"
I.e. upgrade the kernel first or at least install both so that at no time does
the system have to cope with that udev without the newer kernel.
That does of course beg the question of why it needs to ask you to do it, but
perhaps the old kernel is held or something.
