Hm. These are positioned in the lower part of as the crm fonts. And, since
[out of lazyness] the aer fonts def uses the cmr ones by remapping the
names, the ec encoded cmr* fonts are not that suites for math. Sigh. But,
since there is some machinery for independent math fonts, we can redefine
that part. But, since cmr10 is now aer10, we have to make sure that we
bypass the mapper, which can be done [hack hack hack] with a space in front. 

% hack to prevent mapping of filenames, watch the space! 

\definebodyfont [12pt] [mm] [mr= cmr12]
\definebodyfont [11pt] [mm] [mr= cmr10 at 11pt]
\definebodyfont [10pt] [mm] [mr= cmr10]
\definebodyfont  [9pt] [mm] [mr= cmr9]
\definebodyfont  [8pt] [mm] [mr= cmr8]
\definebodyfont  [7pt] [mm] [mr= cmr7]
\definebodyfont  [6pt] [mm] [mr= cmr6]
\definebodyfont  [5pt] [mm] [mr= cmr5]
\definebodyfont  [4pt] [mm] [mr= cmr5]

\definebodyfont [14.4pt,17.3pt,20.7pt] [mm] [mr= cmr12 sa 1]

Later this year those symbols will be mappen in other ways anyway. 

Either add these lines at the end of font-aer or better at the end of
font-cmr and regenerate the format. 

If you want to default to aer: 

texexec --make --bodyfont=aer

will embed these defs
