I'm not sure if this is the right approach - what if a bios 
intentionally assigns a small area? It's dangerous to override the BIOS 
setting.
I'd prefer a kernel command line parameter / module parameter / dmi 
based override instead of an unconditional override based on the minimum 
size.
I'll think about it.
