stupid question i know but - was /boot mounted before doing the copies ?
you mention you have six other kernels on there -- could it be an out of 
disk / inode issue so it looks like it's copied but hasn't ?

please do copy the phrase to this list, I would be interested to know

from the grub2 menu can you choose your old kernels and boot them?
is it sitting waiting for you to press enter but perhaps there is a 
wierd usb-legacy thing in the bios preventing the keyboard working ?

does it appear to acknowledge the pressing of enter by not making you 
wait for the timeout and then just goes to a blank screen ? a flashing 
cursor ?

what about
# cat /etc/portage/make.conf
# gcc-config -l
# uname -a
# ls -lah /usr/src/linux/arch/x86_64/boot/bzImage

I was thinking maybe that you have made another change somewhere that is 
making the compilation of a new kernel skewiff... i.e. it's your 
compiler (build environment) not your grub that might be at fault

again stupid question but have you tried compiling with this option back 
in ?
i.e. could it be somehow silently booting but not updating the screen 
(clutching at straws i know)
