[linux-audio-user] kfusd module (oss2jack) unknown symbols with 2.6.13

Greets to all,
I am experiencing problems during the build (and consequently modprobe)
process of Kor Nielsen hacked version of kfusd module for OSS2JACK,
fusd-kor-1.10-9.

I am on Slackware 10.1, kernel 2.6.13 and 2.6.13.1, gcc-3.3.4, glibc-2.3.4.
As far as kernel version 2.6.12.2 the module has always been built and
modprobed correctly, these are excerpt from console:

root@email-addr-hidden-sal:/usr/src/fusd-kor-1.10-9# make
.
.
[build output...]
.
.
make -C /lib/modules/2.6.13.1/build

root@email-addr-hidden-sal:/usr/src/fusd-kor-1.10-9#

The module does get built, but is not functional:
Upon trying to insmod, or install, depmod and modprobe the module I get
this (quite expecting it...):

root@email-addr-hidden-sal:/usr/src/fusd-kor-1.10-9# modprobe kfusd
FATAL: Error inserting kfusd (/lib/modules/2.6.13.1/misc/kfusd.ko):
Unknown symbol in module, or unknown parameter (see dmesg)

Here is the bottom of dmesg output:

kfusd: Unknown symbol class_simple_device_add
kfusd: Unknown symbol class_simple_destroy
kfusd: Unknown symbol class_simple_device_remove
kfusd: Unknown symbol class_simple_create
kfusd: Unknown symbol class_simple_device_add
kfusd: Unknown symbol class_simple_destroy
kfusd: Unknown symbol class_simple_device_remove
kfusd: Unknown symbol class_simple_create

Maybe something changed in 2.6.13 and introduced this problem?
Has anyone been able to use OSS2JACK with 2.6.13 ?

Thanks in advance!
