ATmega328P targeted at low-power battery use: help needed with baby steps!

Using Arduino Microcontrollers

Anyone got a precompiled 1MHz-friendly ATmega328P bootloader.hex file?

I've tried a few others without success.

I do fine at 8MHz, and have been working on the low power 'scheduler' core for my code instead, with rather more progress!
