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.
