It looks like there is a bug in Qemu (testing boot from Debian 4.0R5 CD):

invalid/unsupported opcode: 1e - 12 - 1b (782106e4) 00000000014080e4 1
IN:
0x00000000014080d0:  mr      r31,r3
0x00000000014080d4:  mr      r30,r4
0x00000000014080d8:  mr      r29,r5
0x00000000014080dc:  mr      r28,r6
0x00000000014080e0:  mr      r27,r7
0x00000000014080e4:  rldicr  r1,r1,0,59

But rldicr should be supported on a 750, according to "IBM PowerPC 740
/ PowerPC 750 RISC Microprocessor User=E2=80=99s Manual".
