You did set the remote target correctly so the output will come from your board.
The /dev/haldiag device may output its data via the GDB channel, in which case it will be shown in
your gdb window. Of course this is heavily depending on your configuration.

If you place a breakpoint on cyg_io_init() you might find how /dev/haldiag is initialized.
This function uses the __DEVTAB__[] that is composed of all the DEVTAB_ENTRY (or CHAR_....)
field in the device files.
You can also enable the CYGDBG_IO_INIT in your ecos.ecc file to get more info during startup.

Debugging this code is great , you should really have a go for this one ;-)
