If you have i have the revision 1293 you are probably going to need to remake the kernel and send those modules (or alternatly remake the kernel and then remake the build-root then reflash the whole gumstix).
see these references:

Hello everybody!

# cd /
# tar xzf /tmp/i2c-modules-2.6.18-1185.tar.gz
# cd /lib/modules/2.6.18gum
# cp modules.symbols modules.symbols.org
cp: modules.symbols: No such file or directory
# ls

# cd /lib/modules
# ls
2.6.18gum      2.6.20-rt5gum
# cd 2.6.18gum
# ls
kernel   mod.dep  mod.sym
# cd 2.6.20-rt5gum
# ls

modules.alias        modules.inputmap     modules.seriomap
modules.ccwmap       modules.isapnpmap    modules.symbols
modules.dep           modules.ofmap        modules.usbmap

which files  i need to change?  which files i need to replace?

Im insert this lines in the bash after this question

# cd /lib/modules
# ls
2.6.18gum      2.6.20-rt5gum
# cd 2.6.20-rt5gum
# cp modules.symbols modules.symbols.org
# cp modules.dep modules.dep.org
# cd lib/modules/2.6.18gum
# cp mod.dep /lib/modules/2.6.20-rt5gum
# cp mod.sym /lib/modules/2.6.20-rt5gum
# cd /lib/modules/2.6.20-rt5gum/
# cat mod.sym >> modules.symbols
# cat mod.dep >> modules.dep
# modprobe i2c-dev
WARNING: Error inserting i2c_core (/lib/modules/2.6.18gum/kernel/drivers/i2c/i2c
-core.ko): Invalid module format
FATAL: Error inserting i2c_dev (/lib/modules/2.6.18gum/kernel/drivers/i2c/i2c-de      v.ko): Invalid module format

Im doing something wrong, or more than one thing
