OK you do not have the xen kernel installed. If you had included
virtualisation in the initial install package selection then you would
have had the xen kernel as well as the normal kernel. xen is one
method to run virtual machines inside your normal operating system.

However you can rule out this factor. Also you have the i686 kernel
which should be fine.

I would certainly not go meddling with kernel recompiling unless you had to.

The kernels made available from the repos have had a lot of work done
to make them work with your distribution.

When you do yum update if there is a new kernel then it is installed
and the mkinitrd is run to generate the initrd file that goes into the
boot area (and must be specific to your hardware).

I presume that you got the newer kernel when you did a yum update?  If
not and you installed your own kernel via another method then I would
suggest you remove it and simply run yum update which will pull in the
latest kernel. For F7 the latest available kernel is 2.6.23.8-34.fc7

I am surprised that you do not have the cache rpm for this latest
kernel, so one thing that you should try is to do
yum update
as root and then try and boot to this kernel.  It would appear that
you don't have this kernel installed, though you could check by doing
rpm -q kernel
and it will list all the installed kernels in your machine.

I am presuming that you have not enabled the updates-testing repo -
new kernels are often placed there for testing before they are put
into the normal updates repo...

Concerning ram - I thought you said you have 1GB of ram?  If so then
that is plenty. On the other hand if you have only 256MB of RAM then I
would very strongly suggest that you increase to 512MB and preferably
more if your laptop will be able to accept it.
