libgl1-mesa-dri:i386 seems to be necessary for DRI on AMD64, but not installable

[bazald]

wine gives an error message (err:winediag:X11DRV_WineGL_InitOpenglInfo Direct rendering is disabled, most likely your OpenGL drivers haven't been installed correctly) without the package installed that is resolved by forcibly installing the package using dpkg -i. Of course, apt requires the package to be removed before updating, and refuses to install the package on its own due to a conflict in i386/amd64 libpciaccess0 packages.

Either this package should be installable to allow DRI to function correctly for 32-bit executables on an AMD64 system, or some other solution that eludes me must be found.
