They are unrelated to glxgears.  When I switch from X to a console, I 
always get these:

   gentoo [drm] Num pipes: 4
   do_IRQ: 0.83 No irq handler for vector
   do_IRQ: 0.83 No irq handler for vector
   do_IRQ: 0.83 No irq handler for vector
   do_IRQ: 0.83 No irq handler for vector

There are no kernel warnings when I switch back to X (other than 
microcode loading and "Num pipes" messages.)

Also, sometimes I get a "do_IRQ: 0.84 No irq handler for vector" (note 
the 0.84, not 0.83).  I was not able to track down when that one happens.


I'm using a vesafb framebuffer (not uvesafb).
