Just a comment on this, I run on an iMX device with an uncompressed kernel for a nice decrease in early boot time. The kernel comes in at 3MB uncompressed and the Qi bootloader I used pulls that in around half a second from uSD. I use gzip for something else as it happens, but in the uncompressed case, boot is not dependent on gzip in the kernel. -Andy
