Okay it was AMD Irongate (751/761) which was compatible with both
Athlon and Alpha 21264 because they shared the EV6 bus protocol:

https://en.wikipedia.org/wiki/Socket_A#Chipsets

But Irongate was paired with a VIA VT82C686B southbridge according
to Wikipedia, and in patch [3/8] of this series you're moving
quirk_vt82c686_acpi() to arch/x86.  That doesn't look right.

Moral of the story is, I'd be very cautious about assumptions
that these chipsets were all x86-only.

Thanks,

Lukas
