The 575 (and 577 and 578) is an All-in-one like the 520/550/560 except it 
uses the '040 and 53C96 instead of the '030 and 5380.  The 580 variant 
uses an '040 and IDE internal disk.

The problem with the 57x has been the mapping and/or video.  We've mapped 
out the ROMs but have never been abe to get to far into the Kernel during 
boot.  It seems to suffer some of the same problems as a couple of the 
PowerBooks in this area.
