Grub MUST MUST MUST MUST MUST support the BIOS device order.

Why must Grub boot with Unix code?  Why cannot Grub boot with whatever 
bootstrap IBM used with the boot manager they shipped with OS/2?  That boot 
manager always respected device order AND it could boot any OS, including 
various Linux of the day...of course...if I remember correctly, that one used 
its own thin boot partition to work its magic.

If the Unix bootstrap cannot directly communicate with the BIOS to determine 
device order and type, then, there is no reason to use the Unix bootstrap 
code, use code that actually works.
