As far as I can see, the code already exists in the kernel to support 
this.  The problem is that this BIOS doesn't define the necessary 
methods (unless I've misunderstood something).  When you say "don't plan 
to support", do you mean that the existing kernel functionality is now 
deprecated, or something?

Thanks,  Phil.
