Yes, IMHO!

I don't know the answer to this one. I'm running the 2.6.10 686 kernel.

I've done this kernel update on three machines. Two desktops and a
laptop, and I didn't have to reconfigure anything else. I just selected
the linux-686 package in synaptic, installed it and rebooted. Don't
uninstall the linux-386 package at this stage!

Apart from a slight improvement in performance, your system will be able
to make use of all your memory. At the moment there is a limit on the
386 kernel which means you are only using about three quarters of a
gigabyte (I can't remember the exact figure).

If for some bizarre reason the 686 kernel does not work on your
hardware, then you can always boot the previous kernel by selecting it
from the boot menu. It should be clearly marked as the 386 kernel. Once
you've done this you can then remove the 686 kernel package and you are
back to where you started.

Have fun!
