I've got a kernel which should slow down the repeat rate to 500ms. Only the custom codes get delayed, so your kenwood-remote should still work properly. I haven't got a pioneer remote, so could anyone verify this? the kernel is a standard 1.02 image with only my ir-patch.
zip-file irtrans1.0.2.zip can be found at http://empeg.dyndns.org/empeg/ir_trans_kernel
