:What's the easiest way to upgrade to the latest set of 2.2.8 srcs ?
:Just grab the latest kernel src tarballs and compile a new kernel ?
You can use cvsup to get the RELENG_2_2 release, which tracks 2.2.x.
I've included a cvsup control file that should work for you. If you
have never used cvsup before, it may take a day of messing around to
get it running smoothly.
cvsup assumes you start out with an empty /usr/src and will populate
it with the source distribution. You need around 330MB of space to hold
the sources, and another 300MB of freespace for /usr/obj in order for
make buildworld to store object object files. If you already have sources
in /usr/src, back them up and start with an empty directory. If all
you are trying to do is to remake the kernel, I still suggest downloading
the entire source tree but you don't need to build the world in that case,
just a new kernel.
If you have your own custom kernel configs in /usr/src/sys/i386/conf,
remember to copy them somewhere before wiping /usr/src and cvsup'ing.
Then copy your custom kernel configs back afterwords.
For 2.2.x I think you also need to softlink /sys to /usr/src/sys.
Once you've setup the space, you can run cvsup with:
cvsup -g -L 2 -h cvsup2.freebsd.org the_supfile_I_gave_you
>>> Please access http://www.freebsd.org/ for more information. <<<
Once you have a working source tree, you should be able to config and
compile up a new 2.2.x kernel.
In regards to running 3.x -- you should try to get your problems fixed
with 2.2.x first rather then potentially compound them by trying to
fix them *and* trying to upgrade to a major new release at the same time.
But once you get these problems fixed, you should work on a plan to move
to 3.x in the next few months since 2.2.x is not really supported any
more. Some bug fixes are being backported to 2.2.x, but generally only
on request or by interested parties.

# to keep your CVS tree up-to-date:
#
# cvsup stable-supfile
#
# If not running X, or invoking cvsup from a non-interactive script, then
# run it as follows:
#
# cvsup -g -L 2 stable-supfile
#
# host=CHANGE_THIS.FreeBSD.org
# This specifies the server host which will supply the
# file updates. You must change it to one of the CVSup
# mirror sites listed in the FreeBSD Handbook at
# http://www.freebsd.org/handbook/mirrors.html.
# You can override this setting on the command line
# with cvsup's "-h host" option.
#
# base=/usr
# This specifies the root where CVSup will store information
# about the collections you have transferred to your system.
# A setting of "/usr" will generate this information in
# /usr/sup. Even if you are CVSupping a large number of
# collections, you will be hard pressed to generate more than
# ~1MB of data in this directory. You can override the
# "base" setting on the command line with cvsup's "-b base"
# option. This directory must exist in order to run CVSup.
#
# prefix=/usr
# This specifies where to place the requested files. A
# setting of "/usr" will place all of the files requested
# in "/usr/src" (e.g., "/usr/src/bin", "/usr/src/lib").
# The prefix directory must exist in order to run CVSup.
# Defaults that apply to all the collections
#
# IMPORTANT: Change the next line to use one of the CVSup mirror sites
# listed at http://www.freebsd.org/handbook/mirrors.html.
