I don't think that was for the 64 bit OS, but rather for 32 bit versions that needed a way to access more RAM. Similar to what you had on windows 2003 Server Enterprise edition 32 bit and above, there was a PAE mode with which you could address more that 4GB RAM.

I've also just checked a 64bit installation of Ubuntu I have, which is based on Debian, and I couldn't find any kernel image for this 64 bit distro that mentioned anything like bigmem or pae...

If I compare this with a 32 bit version of backtrack (also Ubuntu and below that debian based) I can find at least PAE Kernel images, so that would seem to confirm my assumption that you are probably looking at a 32 bit build of the kernel when it says bigmem.

No, for 64bit kernel no need any "bigmem".
