Hello,

Ok, now XFree should find the card.

that's odd, it /should/ get at least as far as vga does.

No, that's a dead end. vga won't get you anywhere on macppc.

Ok, there's your graphics card - 1002,4758 is some ATI device.

> (--) PCI:*(0:15:0) ATI Technologies Inc 210888GX [Mach64 GX] rev 3, Mem @=
 0x81000000/24

and this is what XFree thinks it is.

Yeah, now it's trying to access the VGA framebuffer which is bound to
fail.

Could you please post an XFree log with the ati driver enabled? The ati
driver should know your card, if it didn't then there's something else wron=
g.

have fun
