If the "embedded system" just brews his coffee, then there are not many security issues he cares about. It gets the job done.
Amol, Just add a "mem=4M" to the kernel commandline and see what happens. It depends a lot on what and how many applications you run on that system.
But still, Alan is right. You might run into odd problems that are simply fixed if you upgrade. (My workstation was "pretty good" at staying up under 2.4.2 (about a month at a time), and I didn't want to upgrade, for fear of it getting worse. I upgraded and now get much better uptimes (until my colleague types "reboot -n -f" into the wrong window)).
