This is a known bug in 7.0.  The graphics driver is trying to figure out
the name of the display, i.e., hp98547.  To do this, it must know the
width, height, and number of planes.  It screws up on the 98547 and
thinks that it has 0 planes, and it can't figure out what sort of
display has 0 planes, so it complains to the kernel message buffer.

This bug only affects the crt_name field in the struct crt_frame_buffer_t
returned by the GCDESCRIBE ioctl.

This bug is fixed in post 7.0 releases.
