Disregarding my specific SSH problem, which is probably just config 
somewhere, is there any general reason why it would be a bad idea to 
upgrade the GTA04's Debian rootfs to testing?  Are there any specific 
package upgrades which are known or expected to be problematic?

Also (and slightly relatedly), regarding trying out the 3.1 kernel: is 
it sufficient to unpack the modules into the existing rootfs, and 
install the uImage in the FAT partition?

Thanks,
