[PATCH v6 00/11] Mac Old World ROM experiment

[BALATON Zoltan]

Latest version of this series with addressing review comments, adding
review tags and tweaks to the WIP CUDA I2C support so with this on top
of Mark's screaper patches (with a small fix) the ROM now plays the
startup sound but then gets confused about some memory addresses. I
don't want to debug this further so either some hints are needed what
may be needed or someone could take over and finish these.

I think at least up to patch 8 this could be merged already, the rest
needs more work.

Regards,
BALATON Zoltan
