Good question.  I know that I supported the memcache originally in my
AFS 3.3 Linux-AFS port, and I'm fairly sure the O-A code supports a
memcache on Linux 2.2.  I can't see why it wouldn't work on 2.4.
However I do remember there being some issues with the amount of
memory used compared to the size of the cache in the cacheinfo file,
something like an order-of-magnitude problem or something?  My memory
is a bit fuzzy there.

I seem to recall the cache-size doing something significantly
different on disk v. memory cache.
