2.1.127 opl3sa2 Yamaha OPL3SAx driver works?

[Radu Raduta <radu@mail.dnttm.ro>]

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:

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

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

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 :
