I assume you are connecting to it over the network?  Does it have a
USB port for an emergency attachment of a keyboard?

That is a kernel suitable for Pentium class cpus.

It would be useful to know the information from /proc/cpuinfo.

  cat /proc/cpuinfo

That will tell you the hardware vendor and the specific type of the
cpu.  Depending upon your cpu type a more specific kernel may be more
optimized for your system.

What are you updating it from?

  cat /etc/debian_version

It seems like you might be skipping major releases.  Skipping major
releases isn't supported because you miss the transitions that happen
at major release points.  If that is the case then you should update
to the next major version, and then the next, and so on to get to the
current stable release and don't jump to the current release directly.
Otherwise you may have to deal with additional problems in unique

The /proc/cpuinfo really gives you the right information that is
needed to make this decision.

But...  The 486 is the lowest common denominator and sweeps in older
cpus such as the AMD K6.  So that one would almost certainly be safe
on any x86 system in use today.  As I recall it requires a 586 Pentium
instruction set or later.  Depending upon things you may want to
include it as a failsafe even if you think a more optimized kernel is
the best match.  Otherwise probably the plain 686 is your best match
so you likely want linux-image-2.6.26-2-686.  Additionally you will
want to install the linux-image-2.6-686 meta package so that future
updates are automatically selected.
