Piers,
The SmartMedia card reader should just work. Using a stock 2.4.18-bf2.4
kernel,
all I needed to do was add this line to my /etc/fstab
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/sda1 /smartmedia auto rw,user,noauto 0 0
Then it was just a matter of plug in reader, insert card, and mount. When
finished, unmount, remove card, and (optionally) unplug reader.
In the event that you are using a home rolled kernel, you need to enable
support for SCSI block devices. This is the SCSI part of my .config file
(2.4.20 kernel) that works with the SmartMedia reader:
#
# SCSI support
#
CONFIG_SCSI=m
#
# SCSI support type (disk, tape, CD-ROM)
#
CONFIG_BLK_DEV_SD=m
CONFIG_SD_EXTRA_DEVS=40
# CONFIG_CHR_DEV_ST is not set
# CONFIG_CHR_DEV_OSST is not set
CONFIG_BLK_DEV_SR=m
# CONFIG_BLK_DEV_SR_VENDOR is not set
CONFIG_SR_EXTRA_DEVS=2
# CONFIG_CHR_DEV_SCH is not set
CONFIG_CHR_DEV_SG=m
Everything works just great.
