One problem might occur when the desired device doesn't have
a "PC speaker" functionality and only offers sound output
through the sound card (inside the chipset, which is a chip,
and mostly is the CPU itself). Programming a PC speaker beep
is, as far as I can imagine, more simple to implement than
a sound generation by the DSP (which requires a driver to
do so).

There are also millions of blind people world-wide, but
web developers don't pay any attention on them. :-)

You could initially have a look at the atkbd (or ukbd?)
source files. Maybe just inserting some output of the
ASCII character 0x07 (BEL) after each recognized keypress
would be sufficient, but... no, it won't be that easy. :-)
