Well. FPC can be used to write an operating system, so writing a device
driver is in theory possible.
Mostly, this would mean writing an RTL which runs inside a kernel, which means
writing routines to handle IO and routines to handle memory management from the
I think for Unix-type interfaces that would be enough. For Windows, there is
the additional problem of producing a .sys file, which would mean some changes
to the internal linker.
