I repeated this numerous times on the same computer (where your kernels 
worked) with the stick and the card reader.  I need to hard reboot after 
the crash.  Is there some way I can log what is going wrong?

I compared our configs.

I added usb-uhci (alternate uhci) to your uhci and usb-ohci.

I omitted a few 'experimental' storage device drivers - Freecom, jumpshot 
(this is some card reader -do I need it?) 
ISD200, an HP CD-writer, an ISDN/modem driver.  What is a Freecom USB to 
IDE/ATAPI adaptor, a way to plug in an external hard drive via USB?

I omitted a lot more other things that I doubt have anything to do with 
uhci or storage - multimedia and imaging devices (cameras and scanners), 
network adaptors except for USBNET (for the PDA), port driver (?),
serial convertor (to plug USB into serial ports), misc.

I made sure to include both Sandisk drivers.  My reader seems to use 
SDDR-09.  I included Microtech ZiO! CF/SM reader and datafab reader.

Maybe I need the ISD200 USB/ATA bridge?  It is used for CDRW drivers, 
SmartCable, Jukebox, eXtreme Drive cable (USB-IDE).    How would this 
affect uhci?
