Whats the error when you try to load sdcard.o? It may be as simple as
adding the -f option to the insmod command if insmod is complaining
sdcard.o was compiled for a different kernel.

The SD card driver is only available as a binary module. The reason
being is Technologic Systems had to sign an NDA to join the SD
association which gave them access to the SD card specs. Part of the NDA
stated no source code can be shared that is used to access the SD card.
Due to these constraints Technologic Systems can only provide binary
drivers for the SD card. Although keep in mind there is a sdcore.o
library(OS independent driver) available that has the read, write, and
initialization routines for the SD
card(ftp://oz.embeddedarm.com/sd/sdcore/). The sdcore.h provides the
signatures for these
functions(ftp://oz.embeddedarm.com/sd/sdcore/sdcore.h). There are .o
files for gcc(ftp://oz.embeddedarm.com/sd/sdcore/gcc/sdcore.o) as well
as IAR(ftp://oz.embeddedarm.com/sd/sdcore/iar/sdcore.o).
> Any suggestions for which direction next...
Add the -f option to the insmod command when you load the SD driver.
