Ah, finally! It's quite reassuring to know that I'm not alone in suffering
this severe problem :-)

Hmm, interesting. I assume your problem is very "similar"
(mine just printed: "No such device").
I just did what I had announced (recompile ALSA using older gcc versions
installed on the system).
root@note:/usr/src/system/CVS/alsa/alsa-driver# dpkg -l|grep gcc
ii altgcc 2.7.2.3-2 Alternate gcc package for the libc5 environm
ii gcc 3.2.2-0 The GNU C compiler.
ii gcc-2.95 2.95.4-15 The GNU C compiler.
ii gcc-3.0 3.0.4-0pre0201 The GNU C compiler.
ii gcc-3.0-base 3.0.4-14 The GNU Compiler Collection (base package)
ii gcc-3.2 3.2.2-0pre8 The GNU C compiler
ii gcc-3.2-base 3.2.2-0pre8 The GNU Compiler Collection (base package)
ii gcc272 2.7.2.3-18 The GNU C compiler.
ii libgcc1 3.2.3-0pre1 GCC support library
Using gcc-3.0 in Makefile.conf: failed.
Using gcc-2.95 in Makefile.conf: SUCCESS!!
Sounds as if there might be a pretty severe gcc 3.x ALSA build problem...
As I've got quite some time now, I'll try to nail it down somewhat.
Any further helpful comments strongly appreciated...
Needless to say I'll concentrate on the info.c /proc support area...
Maybe the various /proc parsing handlers inside that file get corrupted
by some gcc optimization somehow...
I'll add some traces to that file to find out more.
