You can always implement it as daemon or something like that that
communicate over a pipe or such thing.

As I said, from interrupt handler you can't call very much and especially
no I/O functions. This stuff must run as kernel thread or something like
that with it's own context or it must run in a process context (btw.
interrupt handlers run without any context, that's why you can only call
specific functions from interrupt handlers).

I think fvdi must be loaded before FreeMiNT? Otherwise it's not cleanly
pushed into kernel space.

Yeah, that would be nice :-)
