I found this: http://code.google.com/p/android-development-environment/wiki/EclaironArmadillo500FX ~ If you read through it there is a small archive with a patch for eclair which will enable ARMv6 native compile instead of ARMv5te. Dunno if you knew about it, or if there are any real performance gains, but thought you might be interested for your AOSP rom :)
