Yup, changing the bx_panic to printf in iodev/pic.cc makes it work. The
patch is:

*** pic.cc 2000/04/01 02:31:42 1.1
--- pic.cc 2000/04/01 02:36:16
***************
*** 294,300 ****
            break;
  
          default:
! bx_panic("PIC: write to port 20h = %02x\n", value);
        } /* switch (value) */
        break;
  
--- 294,300 ----
            break;
  
          default:
! bx_printf("PIC: write to port 20h = %02x\n", value);
        } /* switch (value) */
        break;
