OK, I guess I'm starting to understand how Linux manages disk caching, and the meaning of "buffered". In fact: # free -m total used free shared buff/cache available Mem: 32094 2799 1074 154 28220 28810 Swap: 36168 168 36000 ...so I have 28810MB RAM available.
Well, sort of. You have 1074 MB free for use if anything wants it immediately. The rest of the 28810 MB is being used by the kernel as temporary storage for open disk files etc and will take some cycles to clean out before it can be used by other things. So it is available for allocation to programs, but the alloc will be somewhat slow.
(It's been a few decades since I dealt with these things in detail, so I'm not sure exactly on best practice with these GB-sized machines. But that looks reasonably healthy to me: 1GB RAM free and almost no swapping.)
