I have mobile versions of all my main website pages but a few minor ones are aimed at schools, there is no mobile version and it would not make sense to have one.

These keep bringing up "Text too small to read" errors in Google webmaster reports. I have removed these pages from the Sitemap and added them to robots.txt but that didn't help.

Any solutions, apart from creating completely pointless mobile pages that are not linked to from other mobile pages and will never be visited?

Cheers
