Updating actual kernel code (drivers)

this is old, for the previous 2.6.36 kernel.

a bit more involved, this is not something that you can deal with in pikg.

basically:

change kernel code in

/home/venture/svn/som-9g45/linux-2.6.35.5-clean/

git diff <file> > patchfile to pickup your changes into a patch file

move the patchfile into the bitbake config in /opt/oe/venture-stable-2009/recipes/linux/linux-vr/

add the patchfile to the SRC_URI in /opt/oe/venture-stable-2009/recipes/linux/linux-vr_2.6.36.bb

rebuild the kernel using a ./oe-run -c clean virtual/kernel && ./oe-run virtual/kernel

optionally, deploy everything after running the venture-image as well using the ./deploy.sh script
