You can add debug statements in qemu to the dbdma code (print reads or
writes if channel isn't 0x16 nor 0x1a, they're the ATA channels); if I add
DMA addresses and do this, the first attempted write I see is when I crash
into MacsBug (and only if MacsBug is running). But that might just be
because I'm crashing too early in my test runs, who knows..

I have honestly no idea what a slot is! I have the documentation for it open
.. somewhere. So I'm just assuming/hoping that 1 makes sense.
