Already found that out. As you can see, I use 2.4.27 and thus, I should not
use 2.6.x kernel header files.
I'll file a bug report against kernel-headers-2.4.27-1 since auto builders
cannot do that change. Another work-around is to simple touch the missing
header file.

I manually do now:
cp ../sbri.c alsa-kernel/sparc/
patch -p1 < ../Alsa.patch
#mod-deps binary is not the right one for sparc
rm utils/mod-deps
#create updated acinclude.m4
make all-deps
#create updated aclocal.m4 (probably optional)
aclocal
#create updated configure
autoconf
./configure --with-oss=no --with-cards=sun-amd7930,sun-dbri
make
I cannot compile in the OSS compatibility layer because the Debian Sparc
kernels do not have the proper option enabled :-(
However, I must tell you that compilation of the driver fails:

AFAIK, Kconfig is much advanced in linux-2.6, less automatic in linux-2.4.
Sadly, I cannot use linux-2.6 since SMP is not working, there.
