Nope. But it's still set to 1K for me, and I think I know where the 
problem might have originated from..
I used a generic distro (Ubuntu) config as base when I first built the 
kernel,
and I see that on Ubuntu's 'generic' configs, the value for FRAME_WARN 
is 1K.
(Btw, I did install a 64-bit version of the distro on the system to 
begin with.. guess they just set it to 1K always)

When I do make defconfig, this is set to 2K properly.

Thanks,
