2.1.127 opl3sa2 Yamaha OPL3SAx driver works?

Hi all!
First of all, i'd like to know if this driver (opl3sa2 from 2.1.127 version kernel) is operational, becouse i couldn't make it work, neither as a module, or as a built-in driver.

My configuration is an OPL3-SA3 (i think...), and it works with isapnp & WSS+OPL3+MPU401 drivers. Still, i'd like to see a more specific driver, one that will at least configure my mixer right.

I would like to know if anyone succesfully installed the mentioned driver, and how. It wants several parameters:
=============
io = 0x370 : i used what the "SETUPSA.EXE" program reports for CTRL
wich is configured in the isapnp.conf file as "IO 4" for logical device 0 (is that what LD stands for ?)
mss_io = 0x530 : this is the WSS/MSS io - configured as IO 1 on LD 0
by isapnp
mpu_io = 0x330 : the MPU401 io port - configured as IO 3 on LD 0
irq = 5 : the card's irq - INT 0 for LD 0
dma = 0 : DMA 0 for LD 0 configured as CHANNEL 0
dma2= 1 : DMA 1 for LD 0 configured as CHANNEL 1
=============

On modprobe opl3sa2 with parameters in /etc/config.modules it outputs:

=============
ad1848/cs4248 codec driver Copyright (C) by Hannu Savolainen 1993-1996 done emptying slots

=============

Note that some of the mesages are "home-made" - used printk in the source to see the program flow.

After crashing, it leaves the mpu401, sound and soundcore modules installed, but an
cat /proc/ioports
gives :
