I have a Redhat 6.1 WS that was installed with 64 MB RAM. I added another
64 MB, booted, BIOS sees it, but top, free, etc still see only 64 MB.
Any clues on what to do?

Add mem=128M (or mem=127M if that fails) to the boot line (append in
LILO), or upgrade the kernel to something recent.

Maybe append="mem=128M" in lilo.conf helps ...

Upgrade to linux-2.2.18 or linux-2.4.2.

Also, some motherboards (Abit BH6's comes to mind) with certain older BIOS
won't let 2.2.X kernels see all 128 megs. Check your motherboard makers
website for BIOS update or other like information.
