I have been using Yellow Dog Linux 3.0 on my old Powermac 9500 for 
quite a while.  Except for problems with serial-port printing, I have 
been happy with it.  Now, with the new 4.0 release, YDL has ceased to 
"officially" support pre-G3 machines.  This says to me, "You're on your 
own, Jack."   I would be willing to switch to another flavor of Linux 
or NetBSD if there weren't huge problems getting it to run on my 
machine.  Basically, I use it as a development workstation, not a 
server.

I know that dual-booting with BootX is out, but is there something like 
Mac-on-Linux in the BSD world?

How about serial-port printing?  USB printing?

Using the kernel argument:  video=atyfb:vmode:13,cmode:32 I have X up 
and running just fine.  Can I do the same with NetBSD?

Any advice would be welcome.
