Thanks.

Well... speed allways mathers. I am not using it daily today, but remember 
the time when I was looking for proper module preload configuration for 
some rare scsi device and was building it very often. I am under 
impression that with every kernel build you need to regenerate initramfs, 
to have correct modules loaded on next reboot.. and this I was used to do 
very often. Then every delay counts.

I would suppress them, let them print in "debug" mode.
