Ok, too many changes in radeon. Try this one, specific for 2.6.9. Note
that the same fix is available in the bk or mm tree.

This is the first time I knew about this problem. Note that gpm predominantly uses the TIOCLINUX ioctl which mainly manipulates the screen_buffer. So each time the mouse is moved, gpm sends an ioctl that complements or reverses the attributes of the character underneath the mouse cursor, then it sends a putc command (telling the console to repaint the character). It does not use the fbcon cursor API. In all drivers I tested in the i386, gpm seems towork correctly. I can't really much help in this area except for someone with a PPC machine to debug the TIOCLINUX ioctl and complement_pos in drivers/char/vt.c and the selection code in drivers/char/selection.c.

I suspect as much. I think fbcon_putc might have an endian bug. Can you try
this patch?

Great.

Can you try choosing the l6 color logo in the kernel kconfig. Or you can
try this patch instead. Let me know which one or if both works.
