Well, let's see...

Graham Stoney commented on # 2, so I'll give a try on # 1 :-)

There  once  was  a   bug   with   the   IP   address   handling   in
arch/ppc/mbxboot/misc.c   ;   if   you   can   find   a  place  where
"nfsaddrs_string" you should be able to figure out how to replace the
existing code with the following snippet:

		...
		dp = nfsaddrs_string;		/* nfsaddrs=x.x.x.x:y.y.y.y	*/
		while (*dp) {
			putc(*cp++ = *dp++);
		}
		/* add IP addresses as <my_ip>:<serv_ip> */
		for (i=0; i<4; ++i, ++byte) {
			unsigned char outbuf[4];	/* 3 digits + '\0' */
			unsigned char *optr = &outbuf[sizeof(outbuf)-1];

			*optr = '\0';

			do {
				*--optr = (*byte % 10) + '0';
				*byte /= 10;
			} while (*byte);

			while (*optr) {
				putc (*cp++ = *optr++);
			}

			if (i<3) {
				putc(*cp++ = '.');
			}
		}
		putc(*cp++ = ':');
		...
