Apple has a complete set of images for System 7.5.3 on their web site. It 
is something like 19 image files, but you probably only need the first 
few disks in order to get one that is bootable, and just drag the system 
folder onto your SE/30's hard drive. That should be sufficient to get it 
booting for use with NetBSD (don't forget the Mode 32 init will also have 
to be added to that system folder... you can also get that from Apple's 
web site)
