I managed to build -current so I burned a CD and booted it on a eMac
1.25 / ATI Radeon 9200 (PowerMac6,4).

The first time I booted the GENERIC_MD kernel (netbsd.macppc) the
framebuffer started fine with some light-green letters on white
background.
But radeonfb0 started to print out some debug and error messages and
then the screen went black and the eMac froze  (I suppose, since the
keyboard and mouse were disconnected).

Then I attempted a second time boot, but this time when booted the
kernel, no framebuffer was started: the screen went immediately blank
after the boot command (in case it has any relation with this, this
time the boot  command was not the first command entered on the OF
prompt).

But this time it did not hang and continued the boot process (I
noticed the keyboard lights being activated).
So I blindly typed "S" to get shell and managed to configure the gem0
network, ftp to my other Mac and upload a copy of dmesg:
