It's not just Shark-specific; the ESS 1788 in my laptop is arranged
the same way. The ISA ESS chips have both the system-control-register
and read-sequence-key mechanisms avaliable to set the I/O address, and
one of the input pins on the chip determines which mechanisim may be

So the solution isn't to delete the read-sequence-key code; the
solution would be to add read-sequence-key code and a way to try both.
