BTW... a point on this. As you don't have the LCD_SPU_ADV_REG register,
you probably don't have support for ARGB cursors. DRM only supports ARGB
cursors. You can't down-convert an ARGB cursor to something which looks
reasonable in the kernel, so I'd suggest forgetting hardware cursors.
Even converting ARGB to transparency + RGB looks rubbish and wrong.
