Having written drivers for various operating systems, my immediate
reaction (without looking at the web page you mentioned) is that this
is an idea that makes little or no sense.
Most drivers are largely OS specific code (the actual hardware
fondling is in the minority). Abstracting that in a meaningful way to
a meaningful range of operating systems is unlikely to succeed, unless
you don't mind having no performance at all.
