According to the function NVUseHWCursorARGB() in
xc/programs/Xserver/hw/xfree86/drivers/nv/nv_cursor.c, the hardware does
support it if the cursor size is less than 64x64 pixels.
With the nv driver + Mesa, there are fewer artifacts in OpenGL programs
than with the nvidia driver. But, the cursor still flickers in all of
the other situations - window resizing, rendering webpages, typing in
this window (Evolution), and when swapping GL buffers.
