Hi, Borislav,

Thanks for your contribution. Nice to see a way to get rid of the "program
wdm tried to access /dev/mem ..." messages.

wdm is currently orphaned and no maintainer is explicitly caring of it,
neither in Debian nor upstream. Since I made some of the final QA 
non-maintainer uploads I will care of including your patch at some
time. Note that this will not happen soon since Debian wheezy is
currently in "frozen" state in preparation for release.
