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’s Manual".
