Lexar multi-card reader problems


I had originally posted this over at newbies but received no response. After having read a few helpful pages I have been able to get my RH9 install to recognize my lexar 4 card reader. What I have done:

1. Created the script:

#!/bin/bash
echo "scsi add-single-device 0 0 0 0">/proc/scsi/scsi
echo "scsi add-single-device 0 0 0 1">/proc/scsi/scsi
echo "scsi add-single-device 0 0 0 2">/proc/scsi/scsi
echo "scsi add-single-device 0 0 0 3">/proc/scsi/scsi
cat /proc/scsi/scsi

2. Added the following lines to fstab:

/dev/sda1 /mnt/cfc vfat rw,user,noauto 0 0
/dev/sdb1 /mnt/smc vfat rw,user,noauto 0 0
/dev/sdc1 /mnt/mmc vfat rw,user,noauto 0 0
/dev/sdd1 /mnt/msc vfat rw,user,noauto 0 0

3. Added the cfc, smc, mmc, and msc files to the mnt directory.

The problem(s):
1. I do not know where to put the script. I had it in root but the cd player wouldn't work on loading.
2. The different card formats seem to change their lun position (ie: the mmc device has shown up as both sdb1 and sdc1 across reboots).
3. Can I do away with the script if I recompile the kernel to probe for multiple luns? I believe the answer is yes but need to learn to recompile a kernel at this point.
4. When mounting the device after running the script post-boot I cannot write to the card. My first guess would be that this is an ownership problem but figured I would include this as this is about where I stopped trying to make this work-just building up the motivation for another salvo.
