Question answered, I guess:

"Quark: Improved support for systems that are not cache coherent
Exec: Improved support for systems without cache coherence support
IDE/SATA: Support for systems without cache coherence
USB/PCIUSB: EHCI/OHCI support for machines without cache coherence"
http://www.morphos-team.net/releasenotes/3.8

Btw, Exec note says "Miscellaneous improvements to support the PPC440 family of CPUs". Shouldn't that say "PPC460" like the other notes do?


Edit: Missing cache coherency comes with some limitations, it seems.
