If it's more or less compatible with the current driver, it's fine.
But, one bulk patch is bad. Even if you replace the driver code,
split in a logical order, at best.

If it's a new ioctl, it's OK. We can drop the old (very likely)
unused ioctl eventually. But using the same ioctl for different
behavior is no go.

Well, actually I forget what your questions are. Please continue it
on ML here.
All other sound drivers work fine with more than two periods, so I
don't think there is any restriction in the API side.
