well, with the ms-dos 5.0 himem.sys, you CAN tell it not to eat
all extended memory by specifying /int15=xxxx where xxxx is the 
amount of extended memory (in kb) to leave for int15 access (what
mathematica uses).  also, you'll notice that mathematica will run
in ems, so you can run emm386 on top of himem.sys and use mathematica
that way.  only problem with that is that real mode programs (like
djgpp) will crap out with emm386.
