sb.o under 2.4.nn

[Marvin Stodolsky <stodolsk@erols.com>]

Please respond to me as well as the list.
	I'm having trouble achieving sb.o functionality under 2.4.0-test8
for a ESS1869 card.
Under a custom kernel 2.2.14, sound is set with: 
	/sbin/modprobe sound
	/sbin/insmod uart401
	/sbin/insmod sb io=0x220 irq=5 dma=1 dma16=-1 esstype=1869
which loads:
Module                  Size  Used by
sb                     32724   0  (unused)
uart401                 5904   0  [sb]
sound                  56088   0  (autoclean) [sb uart401]
soundlow                 300   0  (autoclean) [sound]
soundcore               2340   5  (autoclean) [sb sound]

But under a kernel 2.4.0-test8

        /sbin/modprobe sound
        /sbin/insmod uart401
        /sbin/insmod sb_lib
        /sbin/insmod op13
loads:
Module                  Size  Used by
sb_lib                 33704   0
opl3                   11180   0  (unused)
uart401                 6416   0  [sb_lib]
sound                  56640   0  [sb_lib opl3 uart401]
A following attempt to load the sb.o module fails with:
insmod sb io=0x220 irq=5 dma=1 dma16=-1 esstype=1869
Using /lib/modules/2.4.0-test8/kernel/drivers/sound/sb.o
sb: No ISAPnP cards found, trying standard ones...

device
Hint: insmod errors can be caused by incorrect module parameters,
including
invalid IO or IRQ parameters

DMA info is:

After:
	rmmmod sb_lib
There is a dma problem
	cat /proc/dma
outputs:

Segmentation fault

Which is obviated by reinstalling:
	insmod sb_lib
Using /lib/modules/2.4.0-test8/kernel/drivers/sound/sb_lib.o
As shown by:
	cat /proc/dma
 1: SoundBlaster8
 4: cascade

Using 
   insmod sound dmabuf=1
is without manifest positive effect.

Should there be some sound_core.o and sound_low.o equivalents under
2.4.nn ?
Suggestions?
