Did you install kernel-module-i2c-dev? Do you have an i2c dev node then? How
about removing i2c-pxa form the i2c init script?

Something like http://git.angstrom-distribution.org/cgi-bin/cgit.cgi/meta-
angstrom/tree/README and http://sakrah.homelinux.org/blog/2011/03/using-
openembedded-core-to-build-angstrom-for-qemu/
o git clone git://git.angstrom-distribution.org/setup-scripts
o cd setup-scripts
o git checkout origin/oe-core -b oe-core
o add in sources/layers a line with
openembedded-core,git://gitorious.org/schnitzeltony-oe-meta/meta-
freescale.git,master,HEAD
o ./oebb.sh config mx28evk
o ./oebb.sh update
o check if the settings in conf/*.conf meat your directory preferences
o check if you find ${TOPDIR}/sources/meta-openembedded/meta-xfce \ in
bblayers.conf
o bitbake console-image
Hope it helps
