fixed in cvs, will be in next build.

although it's not clear what he is going to fix. 

1)  Neither device is on the whitelist, BUT, each device will work with 
the "first" card slot.

2)  The cards are:
# lsusb
Bus 001 Device 002: ID 0aec:3260 Neodio Technologies Corp.
Bus 001 Device 001: ID 0000:0000
and
# lsusb
Bus 001 Device 003: ID 0483:1307 SGS Thomson Microelectronics Cytronix 
6in1 card reader
Bus 001 Device 001: ID 0000:0000

3)  As a work-around, I re-compiled the kernel (2.6.9-1.681_FC3) and 
checked the box to "probe all LUNS", even though xconfig in that area 
has a note that this can be left unchecked and over-ridden by parms in 
grub and/or modprobe.conf.  THIS WORKS!  Fortunately, none of my other 
SCSI devices gets broken by it. 

So, IMHO, what's broken is the "over-ride" mechanism, or the 
documentation (over-ride isn't intended to work if device not on 
whitelist?).
