Yes, a static /sbin/init should work.

Probably not.  The 440GP has no floating point hardware, so you will
need (at least) to build a special glibc without FP instructions and
also make sure your gcc is set up not to generate FP instructions.

Your best bet is probably to download ELDK (a free Embedded Linux
Development Kit) from www.denx.de.  Dan Kegel also has some good PPC
4xx cross development information at www.kegel.com.

Best,
