Try configuring Cog without libalsa.  e.g.

../../platforms/unix/config/configure --without-vm-sound-ALSA
--without-vm-display-fbdev --without-npsqueak -prefix=/home/qwaq/qwaqvm/
CFLAGS="-g -O1 -msse2 -D_GNU_SOURCE -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1
-DCOGMTVM=0" LIBS=-lpthread

and if you have problems with OSS sound you can disable that too

../../platforms/unix/config/configure
--without-vm-sound-ALSA --without-vm-sound-OSS --without-vm-display-fbdev
--without-npsqueak -prefix=/home/qwaq/qwaqvm/ CFLAGS="-g -O1 -msse2
-D_GNU_SOURCE -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1 -DCOGMTVM=0"
LIBS=-lpthread

that will leave you with vm-sound-null which is fine for a server.
