Questions about using FreePascal to Write Bootloader and Kernel

Are there any FreePascal tools or libraries that allow one to write 
directly to the hardware rather than just to the OS?

I would like to try writing a simple bootloader and Kernel and a 
keyboard and USB driver exclusively with FreePascal-related tools. If 
possible I would like to do it without writing a single line of 
assembler. Instead the tools would create all the assembler.

It seems that FreePascal has a opportunity here to make everything 100% 
cross platform. Do any such tools exist?
