 The PVR is 80010201 so it uses the "7455 others" code.

Hrm... I invite you to read the gazillion errata for this chip rev :(

 Are they available online ?  Would I understand them ?

You should also contact the AmigaOS folks, they might have configured
something in the northbridge in a way that won't work when the M bit is
set but there might be a workaround. I suppose their northbridge spec is
kept behind closed door though, as it is common nowadays :(

Ben.

 Actually, I think it's kept in a locked cupboard in a room labelled
"beware of the leopard", in a basement at the bottom of some broken
stairs.  FWIW, the option biting me is CPU_FTR_NEED_COHERENT - no real
surprises there.

 I'll have another go at trying to talk to them.  Thanks for your
responses.
