The mark-up is very illogical, and probably should not validate.

But both of you seem to work from the assumption that @role is 
only and solely an accessibility feature.

If that is the case, then of course Lynx and other text browsers 
are not supposed to be updated to support the @role attribute in 
any way, and would be right to hide the image.

However, in isn't - or couldn't - that particular IMG element be 
considered having role="button"?

And, thus, if @role is not only an AT features, then even text 
browsers would be required to support @role. And so Lynx would be 
required to somehow make that link available through some kind of 
fallback text.
