[alsa-devel] 1.0.24 alsa-driver compilation problem

I'm trying to cross-compile the latest 1.0.24 alsa-driver for my 
embedded system (using SH4 processor and linux kernel 2.6.35). Before 
compiling 1.0.24 I did turn off the alsa in kernel configuration 
(leaving just Sound card support enabled). So I run as follows:
./configure --with-kernel=<where_my_kernel_src's_are> 
--with-build=<where_my_kernel_src's_are> --with-cross=sh4-linux-gnu-

and then 'make'. However, during 'make' I've noticed the following warning:

WARNING: "register_sound_special_device" 
[/root/alsa-driver-1.0.24/acore/snd.ko] undefined!
WARNING: "unregister_sound_special" 
[/root/alsa-driver-1.0.24/acore/snd.ko] undefined!

and then when trying to insmod the snd.ko module the following error 

snd: Unknown symbol unregister_sound_special (err 0)
snd: Unknown symbol register_sound_special_device (err 0)

thank you for your help,
best regards,
