You will need to create a gentium math mappings on lines of math-eul, 
math-fou, etc. Lets say, you call this family sil.

By default greek letters are taken from the mi and mr family. The 
following may work:

\definefamilysynonyms [sil] [lcgreek] [tf]
% or the appropriate gentium greek font name instead of tf

\startmathcollection [sil]

\definemathsymbol [alpha] [nothing] [lcgreek] ["08]
% Use the greek font location in Gentium. 
% Add similar settings for other greek letters. Look at
% math-tex.

\stopmathcollection

and then

\definetypeface[sil-gentium][mm][math][sil][sil][encoding=\defaultencoding]

Hopefully, this will work.
