Clearly your Gentoo installation has some configuration issues, inc. your 
compiled kernels.  The initialisation scripts and misconfiguration of 
services at boot/default runlevels could be another problem causing it to 
choke.

I suggest that you zcat your Ubuntu's .config file into your 
Gentoo's /usr/src/linux and then run make oldconfig.  That should give you 
the same kernel configuration which you can thereafter peruse at leisure.  At 
the same time I would copy over the CUPS configuration file from Ubuntu to 
Gentoo (but don't try that until you have proven that your new Gentoo kernel 
is still having problems printing).  You can even diff the two files to see 
if there are any significant differences in settings.

HTH.
