The locate db is skipping only /tmp I think. It makes use of an index, 
that's why it's so fast. updatedb is run by cron.daily to update the db. 
If you get something in in-between it won't be able to find it, of course. 
In such a case you run it manually.
Then "locate whatever". Note, that locate doesn't know any wildcards, you 
can only search for literals. For searching for your kernel rpms you could 
either use
locate kernel (which will find a lot ...)
locate .rpm (which will find all rpm files, which is much less)
and then:
locate .rpm|grep kernel
/var/cache/yum/updates/packages/kernel-headers-2.6.18-53.1.14.el5.i386.rpm
/var/cache/yum/updates/packages/kernel-xen-2.6.18-53.1.14.el5.i686.rpm
/var/cache/yum/updates/packages/kernel-xen-devel-2.6.18-
53.1.14.el5.i686.rpm

One should at least try that, yes. I think your answers were all fine, I 
just wanted to say that I agree with Ralph about the find options and the 
usability of that page ;-)
