you stud.  i just did this manually with:

# modprobe scsi_mod max_luns=5   (i guess i could have used 3 here)

then connected the reader with a FAT-formatted CF card already in it, 
and got:

   and mounted /dev/sdb1 just fine.  boy, wouldn't it have been great
if this had been in a wiki somewhere? :-P

yeah ... bugzilla ... RFE ... whitelist ... ok, i'll figure that out.

rday

p.s.  is there some way to list the options with which a module was
loaded?  "lsmod" shows me scsi_mod, but i don't see an easy way of
listing that it was loaded with a given max_luns value of 5.  perhaps
something under /proc?
