I am trying to add a pci puc device to a 7300. (SIIG Cyber Serial Dual
PCI (dual serial), as per http://www.netbsd.org/Hardware/pci.html).
The GENERIC kernel sees it as 

unknown vendor 0x131f product 0x2030 (serial communications, interface 0x02) at pci0 dev 14 function 0 not configure

So, I added (from the i386 GENERIC config):

puc*    at pci? dev ? function ? # PCI "universal" comm. cards
com*    at puc? port ?           # 16x450s on "universal" comm boards

to the GENERIC config file and built a new kernel. The boot traps:

> boot scsi-int/sd@0:0 netbsd 
>> NetBSD/macppc OpenFirmware Boot, Revision 1.1
>> (tsubai@mint.iri.co.jp, Tue Jul 20 01:13:42 JST 1999)

Now, trying to build a kernel with 'makeoptions DEBUG="-g"' for
debug symbols renders it un-bootable. Strip reports:

strip --strip-debug netbsd
BFD: st03461a: warning: allocated section `.bss' not in segment


Booting it gets as far as

> boot scsi-int/sd@0:0 netbsd 
>> NetBSD/macppc OpenFirmware Boot, Revision 1.1
>> (tsubai@mint.iri.co.jp, Tue Jul 20 01:13:42 JST 1999)
no active packageBooting scsi-int/sd@0/netbsd
1893408@0x100000+1532@0x2ce420 
 start=0x100000

and then freezes.

The source base is NetBSD-1.4.1 -release branch, last sup-ed on
October 10. I'll try -current if that would help.

Is the puc device supported in macppc? If not, what would it take to
make it so?
