Today I tried to update my CATS kernel to 1.4ZB, but I got
the following panic during siop attachment:

---
siop0 at pci0 dev 10 function 0: Symbios Logic 53c875 (ultra-wide scsi)
siop0: using on-board RAM
siop0: interrupting at irq 9
panic: bs_notimpl_bs_wr_4 args at 0xf029fb64

Stopped in swapper at	__cpu_Debugger+0x10:	ldmdb	r11, {r11, r13, r15}

siop_reset() uses bus_space_write_region_4(9) to write scripts,
but arm32/footbridge/footbridge_io_asm.S does not have it.
I don't know about ARM assembler, but how difficult
is it to implement this?
