Actually, the ALSA drivers with PnPBIOS support (snd-cs4232, snd-es18xx and
snd-opl3sa2) do not in fact loose any parameters and the few known trouble
spots there are using
modprobe snd-foo isapnp=0 port=...
as their workaround, bypassing all of PnP, and this still works completely
the same as before.
I do not expect any trouble. A few users might have _mistakingly_ added
parameters to an ISAPnP only (as in, not also PnPBIOS) driver due to
googling up your generic bad-advice webforum that said that worked for
someone with a heavy sounding nickname, but we can deal with that.
Moreover, as I've been experiencing on the ALSA list for a while now (where
I've been somewhat responsive to ISA related issues) basically anything but
PnPBIOS/ACPI ISA is mostly dead and as said, with an isapnp=0 in the drivers
there which known issues are using, there's no difference.
Advice is always good, but I'd not put in the ALSA documentation (wrong
place) and even in the changelog it sounds a bit overly alarming in my own
opinion. The expected fall-out is... <crickets>...
