Well, but the same can be done also in protected mode - buffers above 1MB boundary, couldn't? E.g. UIDE use very low conv. mem and very large XMS buffer. Yes it may be advantage to use 2nd CPU core for driver handling but multicore can be done also in 32-bit mode, not long mode only. And 32bit means you can use v86 but long mode doesn' have any counterpart of v86 mode.

Interesting, you write that you already started. Based on what? Are you doing all from the scratch? There is already SeaBIOS - part of Coreboot project that is aimed to do BIOS services. It's opensource and AFAIK it could be also compiled as UEFI CSM module - what you need. You can just extend it by wanted features.
