Even more confusing - you can't get more than 8M in 24-bit mode
unless you have VM on. Perhaps there should be a more informative
message in the About this Macintosh dialog. (e.g., Maximum usable
memory with current Memory Control Panel settings: xxxMbytes).

Another point: is there any good reason the system doesn't use
memory above the 8M limit for the disk cache? It could also use
this space for a second-level TrueType font cache. Perhaps this
kind of trickery isn't considered worth the effort because everyone
will have 32-bit clean machines soon (right?).
