Is the ICE similar to this? :
drivers/mtd/maps/integrator-flash.c: In function 'armflash_probe':
drivers/mtd/maps/integrator-flash.c:262: internal compiler error: in remove_insn, at emit-rtl.c:3803
Please submit a full bug report,
with preprocessed source if appropriate.
If so, I reported that to the compiler guys in ARM and I think it
got fixed in the 2010q3 codesourcery toolchain (not sure where it
is upstream).

Great, I missed that! Feel free to hotplug away in your defconfig.

I'd swap one for one of your boards with the funky PMU, but I think
some people might not be too happy about that.
