there's a little more to it. When running allmodconfig,
CONFIG_ARCH_MULTIPLATFORM is set but none of the other ARCHes
(ARCH_OMAP, ARCH_AT91, ARCH_VERSATILE, etc) are set, so it turned out
that the driver wasn't even included on my build test.

Russell, is this expected (the MULTIPLATFORM thing) ? Just so I fix my
build test scripts to use another defconfig instead of allmod and
allyes.

cheers
