I'd prefer a MEM /C /P, but that's just me as a non-technical guy :)
FreeDOS does have EMM386, but not mentioned on bootdisk for example. http://fdos.org/ripcord/beta9rc5/readme.txt
mentions default config.sys and autoexec.bat for installed systems (in section 'V' )
- no surprise that ATAPICDD did not work well for you, but SHSUCDX 2.1a should really work! Check the SHSUCDX /? output or my sample freedos-config.txt file, as mentioned in one of my earlier mails. Example: LH c:\somedir\shsucdx /d:FDCD0001,N where N is the drive letter. You can also use the CDRcache CD-ROM cache and the LBAcache harddisk / floppy cache and the TICKLE read-ahead tool for floppy and so on :-).
Keep your current cdromdriver, and use it instead of ATAPICDD.
SHSUCDX is autoloading itself into UMB if available (just like CuteMouse), so no need to use LH.
With NOEMS option of EMM386 I get enough free UMBs to load all UMB- compatible drivers into UMB, leaving 622k of low DOS RAM free :-).

SHSUCDX is only 6.5KB, but no buffer elements (read-ahead cache).
DRDOS 7, FreeDOS 5, MSDOS 6 and Win98SE.
Interesting collection. Let me know if you have time for some comparisons / benchmarks / ... ;).
if you change the config.sys from the downloadable bootdisk, [ http://fdos.org/ripcord/beta9rc5/fdos1440.img ] and enable EMM386, you get the following memory usage: (kernel 2034, command.com v0.83-patchlevel3K)

latest HIMEM & EMM386 versions available from (disk image:) http://fdos.org/ripcord/beta9-final/addon/odin7bin.zip
most stable use of this EMM386: DEVICE=C:\FDOS\EMM386.EXE X=TEST
hope this helps,
