This is a great band-aid to the current situation, thanks.

Longer-term, we should look at making aspects of it automatically
generated based on the list of arches in the Release files of the main
and ports archives. Otherwise it will continually require patches.

The sanity tests fail at some point with EINVAL, so the module will fail
to load in turn. Looking at the test itself (__test_eb_bitmaps), it does
no make any assumptions about page size etc. so this "should work".
Taking powerpc with 64k page size for another reference where the tests
work, I'm not sure what exactly could be wrong here.
