tried both, no results. Looks like the OF ROM doesn't load any firmware 
into the ISP - I tried dumping it to the console early in the isp 
driver, got random data, every 2nd byte 0xff. Then I had a look at the 
ROM itself - there's a MacOS driver and some OF glue, no obvious isp 
firmware image - must be there though, or MacOS wouldn't be able to 
boot from it. Maybe it's compressed in some way, but there's no real 
need to do that, the ROM is only 2/3 full ( rest is 0xff ) and the 
firmware image should be only ~10KB or so. Maybe I should try to 
disassemble the ROM and look for parts that don't make sense.

The notice above is 2 years old and from the author of the driver 
that's used by NetBSD - obviously it hasn't been fixed.

have fun
