Hi Jorge,
You'll need to 	adjust the linux config file. For gumstix this is 
linux/kernel/l4_linux_config_gumstix

It may help to do something like the following ($ means command prompt,
# means comment)

$ cd linux/kernel
$cp l4_linux_config_gumstix .config
# comment out line 106 of arch/l4/Makefile
$make menuconfig

# chose your configuration options here - you should see your #
additions to Kconfig files if they worked

$mv .config l4_linux_config_gumstix_jorgesdriver
# uncomment line 106 of arch/l4/Makefile

# then edit the SConscript in the same directory to use your 
# new config file.
