ATA driver should use DMA transfer mode. In addition, we need some facility that would allow the CPU to do other tasks during a DMA transfer, such as uncompression (when a compressed file is being loaded).

A possible way to do this is to enable functions to be registered as hooks in grub_cpu_idle() (idea by Vladimir).

Note: context switching and/or interrupts must be avoided
