I am not sure I understand the relation between fwinfo and <flavour>.modinfo. 
The former to my knowledge is just a list list of all firmware files that are 
included in the kernel binary. I must admit I cannot remember even what that 
info is used for.
The *.modinfo files list modules and related info. Actually right now, only 
lists module names. And adding a version field is extending this. With <space> 
as separator between fields, we could have other separators within those.
What I think is a good idea is to think about adding info for builtin modules. 
That would at least get rid of the additional tweaking when making a module a 
builtin (right now it vanishes from the abi perspective).
