It works with up to date stuffs. That is my latest 2.6 tree with radeonfb and XFree from CVS. Part of the problem is that the firmware sets up a tiled display. I updated my radeonfb to "clear" the various SURFACE_* translation registers (among other fixes). > The clock scaling of the CPU also doesn't work; interestingly at 867 MHz > it's not much faster the my old Ti PB 500 in dnetc RC-5 though the > overall system has a lot faster design. Yup. I need to figure that out. It's possible that it does like a G5, that is boot full speed when you auto-boot and low speed when you boot via OF user interface. There may be need for some thermal control as well. > Also I cannot boot it automatically from network because holding down N > at bootup will not pick up a DHCP address, so I have to type quite a bit > in OF. :( The "N" thing is normal. Apple hacked so that only DHCP servers which know about some special Apple extensions can be used when doing that. The easy work around is to use the syntax: enet:x.x.x.x,file where x.x.x.x is the IP address of the TFTP server and file is the filename. With that in boot-device (or typing boot enet: etc....), the machine will obtain it's local IP from any DHCP or BOOTP server and will then TFTP from the specified host.
