I'm pretty sure that you're right, because the first time I saw a ProFile
it was hooked up to a //e in an Apple dealership.  I remember thinking
that it was annoying because while I was browsing through the monitor the
ProFile would start up AppleWorks if I hit a few carriage returns on
empty lines.  If I had only known at the time what a hard disk could do!

I just ordered an unpopulated Apple-compatible memory card through
Computer Direct for $99.95.  I had to call the manufacturer, SMT, for
tech help, and he suggested using ProDOS volume calls.  I think that's
what Apple intended, and it should be more compatible with other cards.
If you really want speed (I'm not sure how much difference it would make)
you could disassemble the ROM drivers - or just check out the Apple II
Memory Expansion Card Reference Manual, which is listed as a beta manual
in the APDA catalog for $20.  The description mentions "technical
enthusiasts who want their application programs to take advantage of the 
expanded memory features of the card", but I don't know if this is a
guarantee of specific documentation of soft switch address/functions or
not.
