There are non-PnP OPL implementations out there.  My Toshiba Libretto has
one.  But I thought we now had a plain isa front-end to the "ym" driver that
could handle them?  It should probably be in GENERIC, probing at 530,
since that's where the Toshiba laptops all seem to put the chip by default,
and should probe *before* the sb and wss probes, so they don't get the
chip instead.

My Libretto doesn't have PnP at all, AFAICT.  It also has no PCI bus, even
internally, even though it's a P75 -- ISA PIO IDE, and so forth.  Kinda
crummy... I can't imagine it would have cost them much power or space, and
doing a custom chipset must have cost *more*!
