So what do you mean by catchall emulation ? To allocate kind of dummy 32K block and use it when CRAM mode and delete immediately after ? About the way you enable CRAM mode - it would be nice if we agree to use a protocol which real hardware needs. I still hope to be able to execute real hardware BIOSes on Bochs for example ...

Basically, if the total size of all cached areas is not bigger than CPU cache size, no cache line will be evicted and the cache behaves like Cache-as-RAM (CAR). That should be doable in Bochs, KVM and Qemu. Or were you looking for BIOS code to enable CAR? That is indeed processor specific, but any of the existing CAR implementations will work if the catchall emulation is used.
