My 660av boot now and runs pretty reliably, I have compile most of the 
/usr/src tree and a whole kernel with out incident.   However, I have
found that where my IIci would boot with extensions on, it is absolutely
critical that my 660av have extentions OFF.  My present kernel is
a snapshot from about 8/27 or so, and has no special patches, it
is basically a GENERIC kernel with SONIC SBC NCR and a few other things
turned off, I would be happy to mail you the config file and the kernel
if you wish.
