I think this is something for the em8300 driver, and not the VDR DXR3
plugin per se; the DXR3 plugin part is hardware agnostic.  There was
some discussion on the dxr3-devel (ie. the driver) mailing list about
the current WSS patch some time ago.  It hasn't been applied because of
the reasons you stated above.  I suggest asking for help on the dxr3-
devel mailing list.

Thanks.  Luckily, that page will soon no longer be needed, as most of
the stuff has already been applied in the respective upstream
repositories and there will be real new releases of both of them in the
near future.
