SD Card Reader not being recognized

[dave at tokyocomedy.com (Dave Gutteridge)]

I was successful in getting centosplus installed, and it has had some 
effect. CentOS now recognizes an external hard drive that my friend had 
lent me, which is nice.

However, it still does not acknowledge my SD card reader.

Is there anything else I can do? There must be some kind of support 
available, even if it's bleeding edge, as my SD card reader was possible 
in Fedora Core 4.
