cd into the gumstix-buildroot directory
make defconfig
make

I get an image of around 3.6 Mb.

This is an environment variable set in u-boot, called bootargs.

This page:
<http://docswiki.gumstix.com/U-Boot>
has some information on using u-boot. To se the bootargs for  kernels
newer than 774, you drop into u-boot and then do:

setenv bootargs console=ttyS0,115200n8 root=1f01 rootfstype=jffs2
reboot=cold,hard
saveenv
reset
