Hi Jeff,
I'm filing a new bug report to keep track of progress on this. Please
consider using reportbug or manually submitting a bug report via
e-mail for any future requests, rather than directly contacting the
maintainers/uploaders of a package.
Have you already contacted the upstream pygame developers and notified
them of this issue? Ideally, instead of applying another
Debian-specific patch to pygame, you should ask upstream to remove
-D_NO_MMX_FOR_X86_64 prior to their next release so that all
downstream distributions can benefit from the change, not just Debian.
