I think we'll resolve this by shipping two versions af cdrecord, one
compiled with -DUSE_USGSHM and the other one without it, using a
simple wrapper skript to choose the correct one at runtime:
#bin/sh
VERS=`/sbin/kernelversion`
case $VERS in
2.0|2.2)
exec cdrecord.shm "$@"
;;
2.4|*)
exec cdrecord.mmap "$@"
;;
