if you switch to imx_2.6.35_maintain branch instead of older
rel_imx_2.6.35_11.09.01 actually used in the defconfig, you will get
(among other fixes) these patches :
http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/commit/?h=imx_2.6.35_maintain&id=96a7591a6f72db6d7bb337e78d61c53f670d9793

and I believe the kernel built with recent gcc will run as it runs fine
on i.MX53 when built with Yocto.

Best regards,
