Seems odd to me - why can't the splash screen app in initrd just issue
the call to turn off the cursor - or is this splash screen coming from
something else ?

Either way the implementation in your patch is butt-ugly adding an extra
special case all over the place.

IMHO
- If the splash screen is kernel based then the splash screen module
needs to be able to ask the vt driver itself
- If not then the user space can use ioctls like everyone else (see
setterm)
- It should be implemented without adding an extra condition to a pile of
ifs (or the condition mess at least become a single cursor_visible_p())
