|   Under normal circumstances no OS that I know of traps I/O access
|with debug registers.

Even if an OS would enable I/O BPs, the I/O access still works
since IOBPs and DBPs are traps, not faults.

|Tho if you wanna to be{*filter*}y, add before writing
|to ports something like:
|
|sub eax, eax
|mov dr7, eax

The mov to dr7 will generate #DB if DR7.GD=1 so you'd also have
to install a #DB handler.
