aahz is an A2k with ZorroII only, so I guess it can not work there. But I have another A3k, without any turboboard or network card (though I read that Jens is designing a 100Mbit card...). > It should be noted as well that, although the BRP will work in those hosts, > the memory will have a maximum throughput of 12-14 MB/s which is > significantly slower than the 40-60 MB/s you'll usually get from the memory > directly attached to the accelerator cards.

Sounds like a plan, but I have some doubts that the Debian project will reimburse us for this. According the the current rules, m68k will never be able to qualify as a release architecture (no new hardware, no support, but you said you can control your Amiga via serial console?)
