D'oh, the answer was right in front of me. I forgot that the old Big 
Brother had a bb-memory.sh script that it used to generate that data, so 
all I had to do was replicate it, since Hobbit has that nice backwards 
compatibility built into it for the old clients. Just make your devmon 
messages file look like:
         Memory          Used            Total   Percentage
{percMemUsed.color}     Physical        {megMemUsed}M 
{megMemTotal}M  {percMemUsed}%

And a transforms file like:
MemTotal        : MATH  : {MemUsed} + {MemAvail}
xpercMemUsed    : MATH  : ({MemUsed} / {MemTotal}) x 100
percMemUsed     : REGSUB : {xpercMemUsed} /(.*)\..*/$1/
megMemUsed        : MATH  : {MemUsed} / 1024000
megMemTotal       : MATH  : {MemTotal} / 1024000
