you use powerpc for test this problem???

if your see the lines 715 to 727 from /usr/sbin/alsaconf

    715     #
    716     # PowerMac
    717     #
    718     if grep -q MacRISC $PROCFS/cpuinfo; then
    719     MODDIR=/lib/modules/`uname -r`
    720     find $MODDIR -name 'snd-powermac' -print | \
    721     while read i; do
    722         i=${i##*/}
    723         i=${i%%.o}
    724         i=${i%%.ko}
    725         echo "PowerMac $i" >> $FOUND
    726     done
    727     fi

1) you can see, this lines are specific for powerpc architecture.

2) in the line 720 look for the module for powerpc named, in my case
"/lib/modules/2.6.15-1-powerpc/kernel/sound/ppc/snd-powermac.ko" but the
name doesn't match with the pattern used, doesn't return results, and
never goes inside of the while (line 721 to 727) and for this reason
doesn't found the module to use.


then if you put the asterisk in the line 720 and then the line look like
"find $MODDIR -name 'snd-powermac*' -print | \"

1) in the line 720 the find returns  (in my case)
"/lib/modules/2.6.15-1-powerpc/kernel/sound/ppc/snd-powermac.ko"

2) in the line 721  the variable "i" is assigned the value
"/lib/modules/2.6.15-1-powerpc/kernel/sound/ppc/snd-powermac.ko"

3) in the line 722 cuts the basedir found at left of the filename, this
is "/lib/modules/2.6.15-1-powerpc/kernel/sound/ppc/", and the new value
of "i" is "snd-powermac.ko"

4) in the line 723 cuts the string ".o" from the value of "i", but how
the value of i not finish in ".o" nothing change

5) in the line 724 cuts the string ".ko" from the value of "i", and the
new value of "i" is now  "snd-powermac"

6) in the line 725 print the string indicating the module is found :)

the rest is history.

BTW sorry for my english, and hope its helps.

nueces...
