My memory sticks and similar devices work just great (kernel 2.6.6 on

That indicates that sda1 is not the right device, or else your memory
stick is hosed. Assuming you verified the unit on a different system,
then the hardware is fine.

These aren't relevant to this problem. ac97 is a sound card driver.
via-rhine is a network driver, and the other two pertain to keyboards
and input (usb-related, IIRC).

You also need to have 'sg' (scsi generic) and probably also 'sd' (scsi
disk) loaded.
Make sure you have hotplug installed; it greatly simplifies and
automates these scenarios. The kernel will tell hotplug when it sees
new devices and when devices go away. hotplug will then load any
modules that it sees as relevant. I also recommend 'udev'. With udev
you can set up rules so that your devices will always have consistent
and meaningful names. For example, the following abbreviated lines
from my fstab:
/dev/usb-stick-pny /media/usb-stick-pny auto defaults,noauto,nodev,user,rw
/dev/usb-stick-micro /media/usb-stick-micro auto defaults,noauto,nodev,user,rw
/dev/sd-reader /media/sd-reader auto defaults,noauto,nodev,user,rw
/dev/cf-reader /media/cf-reader auto defaults,noauto,nodev,user,rw
This covers the two different memory sticks I have and the
CompactFlash and SD (SecureDigital) card readers. It doesn't matter
which one I plug in first, because instead of sequential names like
'sda', 'sdb', and so on they are given the symbolic names you see in
my fstab.
