Can't one simply do something like:

char device_string[20];
int i, type, major=0, minor=0;
for(i=0; i<26; i++) {
snprintf(device_string, sizeof(device_string), "/dev/hd%c", 'a'+i);
if ((fd=open(device_string, O_RDONLY | O_NONBLOCK)) < 0) {
continue;
}
switch ('a'+i) {
case 'a':
major=3;minor=0;
break;
case 'b':
major=3;minor=64;
break;
case 'c':
major=22;minor=0;
break;
case 'd':
major=22;minor=64;
break;
.....
}

etc.... to detect the available ide devices without groveling
through /proc/ide?
