Writing drivers...

[1382]

Would it be possible to write a driver completely using C and no Assembler?

Yes. and that's how it should be done. You can map i/o ports(of some devices like PCI) to the address space, and work with them without using asm. But this is not an easy thing:)

In Linux, many drivers use no assembly, or at the very least just as glue
