So this seems to be the missing sound device (maybe trying to play the 
startup chime). Adding some dummy implementation there gets me a little 
bit further:

      2 macio: screamer read 20  4
      1 macio: screamer write 10  4 = 600000
      1 macio: screamer read 10  4
      2 macio: screamer read 20  4
      1 macio: screamer write 10  4 = 8220000
      1 macio: screamer read 10  4
      1 macio: screamer write 10  4 = 0
      1 macio: screamer read 10  4
      7 CUDA: unknown command 0x22
      2 macio: screamer read 20  4
      1 macio: screamer write 10  4 = 180000
      1 macio: screamer read 10  4
      1 CUDA: unknown command 0x22
      1 macio: screamer read 0  4
      1 macio: screamer write 0  4 = 11050000
      1 dbdma_unassigned_flush: use of unassigned channel 16
      1 dbdma_unassigned_rw: use of unassigned channel 16
      1 Unassigned mem write 0000000000240020 = 0x10006238
      1 Unassigned mem write 0000000000240024 = 0xffe32c00
      1 Unassigned mem write 0000000000240028 = 0x0
      1 Unassigned mem write 000000000024002c = 0x84006238

then stops here, I guess it may be waiting for an interrupt so probably we 
need Mark's screamer implementation to move on. Mark, any chance you can 
look at this sometimes? Why is your email address stripped from emails 
coming from the list? Is that a list setting to exclude you from replies?
