Here's a 'ROM dump' of the Garminfone A50, 2.1-update1, kernel v2.6.29. I compiled the zImage/Image from the source code released by garmin-asus using asus_defconfig(pulled and renamed from config.gz).

The files contained in this zip are:
asus_defconfig
Image
zImage
config.gz
system.info.gz
system.tar.gz
boot.img
recovery.img

I'd also like to point out my objective is to get CyanogenMod 6/7 on our Garminfones. I could absolutely care less about the Garmin Navigation features at this point.
