I also use such a start partition, without problems. No start of AmigaOS 
needed.

Some parts of the 53c770 isn't configured by the driver (especially the 
scsi burst mode) and needs to be initialized by the CSPPC-firmware. This 
is normaly done if the Amiga is switched on.
But maybe the different firmware-versions behaves different. As far as I 
know, the newest can be found at:

ftp://ftp.meanmachine.ch/pub/amiga/ppclib

Will be nice if you can check out your version.

Don't know. "IRQ_AMIGA_PORTS" is used and is stolen from other 
scsi-drivers.
